  • Fatigue crack extension mechanism and mode-type analyses of martensitic steels for proposing fatigue strength evaluation method: Example of 18% Ni BCC martensitic steel

    The fatigue properties of martensitic steels tend to differ significantly from those of low- and medium-strength steels. Even if the hardness is the same, the fatigue strength varies substantially depending on the microstructure. Thus, for using martensitic steel rationally and developing materials with high fatigue strength, it is desirable to establish a fatigue strength evaluation method that can consider the microstructural effects on fatigue properties. For this purpose, 18% Ni bcc martensitic steel was used as a model metal to conduct rotating-bending fatigue tests in this study. The fatigue crack behavior on the smooth specimen surface was examined, and the fracture surface morphology on both sides of the broken specimen and the microplastic strain distribution near the fatigue crack tip were analyzed. The results clarified the mechanism underlying fatigue crack extension (FCE). The analytical results revealed three types of FCE mechanisms dependent on the stress amplitude, stress state (i.e., plane stress or plane strain), and martensitic microstructure. Considering these mechanisms, a unique stress–life curve was predicted, and a particular fatigue crack shape and fractography were confirmed. The material indices were speculated to be the representative properties of martensitic steels.

  • Crack growth behavior in air and hydrogen of iron-3% silicon single-crystal thin sheet

    Thuong H.T., Hamada S., Tsuzaki K., Noguchi H.

    Publisher:AIP Conference Proceedings  

    Effects of hydrogen on the macroscopic behavior of crack growth in a thin sheet of single-crystal Fe-3wt%Si alloy were investigated. The center-cracked specimens were tested under a sustained load in a hydrogen environment while under continuous stretching in an air environment. A comparison between the macroscopic behavior of the specimens tested in hydrogen and air was made to elucidate the effects of hydrogen. The results show that hydrogen lowers the driving force for crack growth in the hydrogen environment. COTA is approximately constant in a hydrogen environment while it slightly increases in an air environment. Also, the necking region near the crack tip during crack growth increases linearly with the crack length in both environments; however, at the same crack length, a smaller necking region is observed in the hydrogen environment. Since the necking region can be regarded as the measure of the crack-Tip plastic zone size, the necking region is speculated to increase linearly with the crack length, which is consistent with Dugdale's equation formulated for a perfect plastic body.

    Language:English   Publishing type:Research paper (scientific journal)  

    The present study addresses the damage evolution mechanism in precipitation-strengthened Fe–Ni–Cr-based steel (SUH 660) at ambient temperature in air. Specifically, damage quantification and associated microstructure characterization were performed. The damage initiation sites were inclusion and grain boundaries impinging dislocation slip. The early stage of damage evolution was observed before necking of the specimen. Subsequent plastic straining caused damage growth along slip planes and coalescence of damage via localized shear in ligaments between damages, for which the behavior was associated with the planar character of the slip. The damage evolution behavior observed in the post-mortem specimen was consistent with fractographic characteristics.

  • 115 MPa水素ガス中におけるSCM435の水素誘起き裂進展下限界値KI,Hを求める試験方法 Reviewed

    In order to investigate the suitable test methods for determining threshold of hydrogen-induced crack growth, KI,H, JIc, none-unloading JIc, constant-load and constant-displacement tests were conducted in 115 MPa hydrogen gas at room temperature, using SCM435 low alloy steels whose tensile strengths were between 824 and 1127 MPa. Constant-load and constant-displacement tests have been standardized by ASME KD-10 for determining KI,H in hydrogen gas. JIc test has been standardized by ASTM E1820 for determining fracture toughness JIc or KIc in air. Recently, JIc test was done in hydrogen gas to obtain KI,H. In this study, there were many cases when JIc tests were not conducted in hydrogen gas, because CT specimens broke before the first unloading. Then, none-unloading JIc test, where unloading processes were eliminated in JIc test, was employed in hydrogen gas. All four tests were done under small scale yielding in 115 MPa hydrogen gas. KI,H obtained by four tests was almost the same. KD-10 demands that constant-load and constant-displacement tests of ferritic steels such as SCM435 are done for 1000 hours. Contrary to this, none-unloading test at displacement rate of 2×10-3 mm/s was finished within one hour. It was concluded from these results that none-unloading JIc test was the best test for determining KI,H in 115 MPa hydrogen gas. On the other hand, JIc test was the only test for determining KIc in air, because KIc was obtained under large scale yielding.

    A case study of a cooling pipe for a pre-cooler used in a 70-MPa hydrogen station
    Copyright © 2017 ASME. A case study was conducted on the cooling pipe of a pre-cooler which had been used in a 70-MPa hydrogen station demonstration project. The cooling pipe consisted of a main pipe, a mechanical joint pipe and a mechanical joint. The main and mechanical joint pipes had been joined using TIG welding. Through chemical composition analysis, microstructure observation and Vickers hardness measurement, it was revealed that the main and mechanical joint pipes had been manufactured from SUS316L and that 316L was the filler metal used for TIG welding. Round-bar specimens were machined out of the main pipe in order to investigate the tensile properties of the base metal. On the other hand, both round-bar specimen without reinforcement and square-bar specimens with reinforcement were fabricated from the weld-joint. Using the three types of specimens, slow strain rate tensile tests were performed in 0.1 MPa nitrogen gas and in 115 MPa hydrogen gas at a temperature of -40 °C. Reduction of area (RA), φ, for the round base-metal specimen, the round weld-joint specimen and the square weldjoint specimen were respectively, 83.5 %, 71.3 % and 81.4 % in nitrogen gas, whereas the related values in hydrogen gas were 60.1 %, 61.3 % and 40.1 %. In other words, the RA for the three types of specimens was smaller in hydrogen gas than in nitrogen gas. Dimples were formed on the fracture surfaces of the three specimen types in nitrogen gas, whereas both dimples and quasi-cleavages were formed in hydrogen gas.

    Influence of RTA parameters on residual stress and stress gradient of multilayered LPCVD polysilicon film
    This paper reports the experimental results of examining the residual stress and stress gradient of LPCVD multilayered polysilicon film according to various rapid thermal annealing (RTA) in a nitrogen atmosphere. In particular the stress gradient of multilayered polysilicon film ranging from -17.1 to +1.5 MPa/μm as the RTA processing time increased could be reduced to nearly zero by selecting the appropriate RTA time. The mechanism responsible for this dependence was examined by using both experimental data and material analysis using secondary ion mass spectroscopy (SIMS) and transmission electron microscopy (TEM). It is concluded that the shift of the stress gradient is mainly caused by the thin nitride layers at surface and interface of multilayered polysilicon film.

    Stress concentration and surface roughness effect on strength of polycrystalline silicon structure
    In order to clarify the stress concentration and surface roughness effect on strength of the polycrystalline silicon (poly-Si) structure, bending tests of poly-Si microcantilever beam specimen and surface roughness measurement is performed. The bending test results are analyzed by means of maximum stress at the notch root calculated by FEM models, and it is found that this approach cannot describe the test results. Therefore, modified approach is taken into account by use of two parameters that are the maximum stress and area where stress is larger than 50% of the maximum stress, which indicates stress extension around the position of maximum stress representatively. By this two parameters approach, the test results are explained quantitatively and a strength design chart for stress concentration area of the poly-Si structure is obtained. On the other hand, relationship between strength and surface roughness are confirmed and useful information for the process quality control are obtained. Copyright © 2005 by ASME.

    Strength reliability of micro polycrystalline silicon structure
    In order to evaluate strength reliability of micron size polycrystalline silicon (poly-Si) structure, bending tests of cantilever beam and Weibull analysis are performed. Recently, the importance of microelectromechanical systems (MEMS) in society is increasing, and the number of production is also increasing. The MEMS devices, which contain mechanical movement, have to maintain their reliability in face of external shock, thermal stress and residual stress from manufacturing processes. In greeting the mass production era of the MEMS, in case the material strength design of MEMS is performed, required strength data is not average value but the variation, especially minimum value of the material. Micron size poly-Si structure is widely employed in the MEMS such as microsensor, switching device and so on. Then, in order to evaluate strength reliability of micron size poly-Si structure, tests and analysis are performed. The specimen is made by chemical vapor deposition (CVD) process and thickness is 3.5, 6.4 and 8.3 micrometer and the specimen has notch. The test specimen used for the test changed characteristics of (1) film thickness (2) stress concentration, and investigation about the influence each effects of the variation in a bending strength are discussed.

    Proposal of estimation method for notched specimen fatigue limit of commercially pure titanium
    In order to identify the fatigue limit for a sharp notched specimen of commercially pure titanium, rotating bending fatigue tests on smooth and notched specimens were curried out. In previous studies, it was found that the fatigue limit for a sharp notched specimen of commercially pure titanium could not be determined and it is not sure whether it fail over N=10 7 cycles or not. Based on the experimental results, in the smooth specimen and notched specimen (p=1.0mm), they have fatigue limits and knee points, while the sharp notched specimen (p=0.1mm) does not. As an estimation method, the fatigue crack initiation of each specimen was then investigated. The investigation results are as follows. (1) The proportional relationship exists between the maximum stress K iωa at the notch root and logarithm of the number of cycles to fatigue crack initiation N i. (2) Based on the slope of the relationship between the maximum stress K iωa and the number of cycles to fatigue crack initiation N i at the notch root, there is no possibility that the fatigue crack in the same mechanism initiates over N=10 7 cycles. Therefore, the stress amplitude that is not initiated the fatigue crack at N=10 7 cycles is the fatigue limit.

    Microscopic deformation behavior of lamellar pearlite steel
    Fatigue ratio of lamellar pearlite steel used for railroad rail is lower than the ratio of general steels. The reason is not clarified. It is reported the direction of lamellar microstructure in lamellar pearlite steel effects fatigue characteristics. In order to clarify microscopic deformation behavior of lamellar microstructure considered to effect fatigue characteristics, static tensile tests of lamellar pearlite steel was conducted, in this report. Using the plastic replica technique, microscopic deformation behavior, the initiation and propagation of micro crack was observed. By the observation, it is clarified that the crack initiates but does not propagate during static tensile test. The authors presume the fatigue of lamellar pearlite steel as follow: The grain size crack initiate at initial stage of fatigue process, and the crack act as initial defect of the lamellar pearlite steel. Based on the presumption, the fatigue limit of the lamellar pearlite steel was predicted, and the fatigue limit was confirmed by fatigue tests. As the result, the predicted fatigue ratio are 0.32~0.33 which show good agreement with the fatigue test result.

    Strength evaluation of polycrystalline silicon structure considering sidewall morphology
    In order to evaluate strength of micron size polycrystalline silicon (poly-Si) structure for MEMS considering surface morphology difference between top and sidewall and effective surface area, bending strength tests of cantilever beam, surface roughness measurement and fracture surface analysis are performed. The specimens are made by CVD process for poly-Si deposition and deep RIE process for sidewall formation, and then the surface morphology of the top and the sidewall surface are different. The various size notches on the specimen are introduced in order to change effective surface area. By the fracture surface analysis, it was found that the fracture initiation point was not always maximum stress point; this is because there exist stress concentration on the surface. Surface roughness was measured using atomic force microscope (AFM). Then the maximum stress concentration of the specimen on the top and the sidewall surface respectively were presumed using extreme statistics, and effective surface area was defined. Then, bending strength and effective surface area shows good correlation.

    Measurement of effective stress intensity factor range of Mode II fatigue crack propagation
    Many rolling contact fatigue failures, such as those that occur in railway rails, rolling bearings and gears, is due to the high repeated shear load. In order to prevent such fatigue a failure, the resistance of the material against such a load must be determined. The fatigue crack growth rate is dependent on the stress intensity factor range of the Mode II Δ KII. However, the Mode II crack propagation characteristic varies according to different experiment methods. Therefore, in this study, we measured the effective stress intensity factor range of the Mode II Delta; KIIeff. As it is difficult to carry out the Mode II fatigue crack propagation in the laboratory, this test was carried out using a bending load in this study. This bending load was applied to the tips of a double cantilever specimen and the Mode II fatigue crack propagation could be carried out between the two cantilevers. Furthermore, in order to measure the Δ KIIeff, several strain gauges were applied to the specimen around the crack tip. Using this technique, some Δ KIIeff value during the Mode II fatigue crack propagation tests will be reported. © 2011 Published by Elsevier Ltd.

    Fatigue strength properties of precipitation strengthening stainless steel A286 focused attention on small fatigue crack behaviour
    In order to safely use precipitation strengthening type A286 stainless steel in high cycles, the fundamental fatigue strength characteristics were investigated using fatigue tests at room temperature. During the fatigue test, the author paid attention to the behaviour of small fatigue cracks in order to clarify the fatigue strength properties in more detail than the usual fatigue test. As a result of the fatigue test, the fatigue strength characteristic of the A286 steel became clarified as shown below. The fatigue strength ratio of the A286 steel is lower than 0. 5 which is the ratio value of most steels. The cracks propagate which result in a failure even after 107 cycles. It was found that there are two crack mechanisms propagation of the A286 steel; i.e., in a high load-stress, the cracks monotonously propagate and result in failure. Under a low load-stress, the cracks intermittently propagate even after 107 cycles. The non-propagating cracks coalesce with a new crack which initiates near the crack tip and it becomes longer, finally resulting in a failure. This is the reason why the fatigue failures occur even after 10 7 cycles. © 2011 Published by Elsevier Ltd.

    Fatigue limit evaluation considering crack initiation for lamellar pearlitic steel
    In order to evaluate the fatigue limit of lamellar pearlitic steel used for railroad rails, tensile tests and fatigue tests are performed. Although the fatigue ratio of the lamellar pearlitic steel is lower than that of general steels, the reason for this has not been clarified. The fatigue cracks of the pearlitic steel initiate at a very early stage during the fatigue test. It is speculated that the steel should be treated as a steel with initial defects. In order to determine the initial defect size of the ultra-low cycle fatigue test, tensile tests are performed. Based on the test results, it was clarified that the crack initiation size depends on the crystal structure. In order to predict the fatigue limit of the pearlitic steel, Murakami's prediction method is applied to the steel. The measured defect sizes are applied to the method, and the fatigue tests are performed. The predicted fatigue limits and the test results have good agreement. In addition, from the SEM observations, the initial crack causing the fatigue failure was found to be a pearlite block. We then concluded that the fatigue limit of the pearlitic steel can be predicted by Murakami's method and the defect size is the pearlite block size. If the pearlite block sizes then become small, the fatigue limit of the pearlitic steel will increase. © 2011 Published by Elsevier Ltd.

    Characteristic of threshold stress intensity factor range for small crack on magnesium alloys
    In order to propose a prediction expression of a threshold stress intensity factor range (AKlh) for magnesium alloys with small crack, rotating bending fatigue tests in three magnesium alloys which have a different hardness and low carbon steel (JIS S10C) were carried out. In these tests, the AK of a crack propagation lower limit from an annealed pre-crack as the AKlh was measured. One of the three magnesium alloys have the same Vickers hardness (HV) as the low carbon steel, however the AKth was half of the low carbon steel. In order to make this difference clear, the authors focused on an effective threshold stress intensity factor range (AKeffth), because there is large difference in the AKeffth which is not negligible to evaluate the AKlh between magnesium alloys and steel. Considering the difference in the AKefflh, a prediction expression was proposed based on Murakami's prediction expression which can predict the AKlh in various metals by applying only two parameters i.e. the HV and an initial crack size. However, the prediction expression cannot evaluate the AK th of the magnesium alloys. In this expression, Young's modulus which is proportional to the AKeffth was used to modify Murakami's prediction expression. In addition the new prediction expression was speculated to be accurate. © 2011 Published by Elsevier Ltd.

    The effect of prestrain on fatigue property of precipitation strengthening stainless steel SUH660
    In precipitation-strengthened steel, precipitation particles are considered to be cut by the prestrain treatment and affect the fatigue property of the steel. In this study, fatigue tests on prestrained specimens were performed to investigate the effect of the prestrain and precipitate cutting on the crack initiation and propagation characteristics of precipitation-hardened stainless steel (SUH660). Plain specimens were used to observe the process of crack initiation and propagation. The fatigue life was divided into the crack initiation life and the crack propagation life. The results of the fatigue test showed that the crack initiation life of a prestrained specimen was longer than that of a nonstrained specimen. The observed crack propagation mode was mainly Mode II. The measured crack propagation life of the prestrained specimen was shorter than that of the non-strained specimen, which was the opposite of the results observed for carbon steel. It was assumed that this was because Mode II crack propagated more easily and faster in the prestrained specimen, where the precipitates were cut, than in the non-strained specimen. Therefore, the relationship between the fatigue life of the prestrained specimen and the non-strained specimen is considered to be dependent on the stress level. When the crack propagation life governed the fatigue life, the fatigue life of the prestrained specimen was shorter than that of the non-strained specimen. However, when the crack initiation life governed the fatigue life, the fatigue life of the prestrained specimen would be longer than that of the non-strained specimen.

    Relation between fatigue crack initiation and structure in pearlitic steel
    To clarify the relation between fatigue crack initiation and the crystal structure in pearlitic steel used for railroad rails, fatigue tests are performed, focusing on crack initiation. Then, the fracture surfaces are analysed using a scanning electron micro-scope (SEM). To observe the crystal structure, before the fatigue is performed, the specimen surface is etched chemically. The crystal structure of pearlitic steel, is comprised of "pearlite colonies" which have the same lamellar structure direction, and "pearlite blocks" which have the same ferrite crystal direction. A fatigue crack initiation region should be affected by the crystal structure; however, the relation between the crack initiation region and the crystal structure in pearlitic steel has not been clarified. From the fatigue test results, the fatigue crack of the pearlitic steel was initiated at a very early stage of the fatigue test. To determine the unit of fatigue crack initiation in pearlitic steel, the relation between the crack initiation region and crystal structure was clarified by using SEM analysis.

    Evaluation of joint defects on FSW of mg alloy using statistical method
    To select the welding conditions that can ensure a particular fatigue strength for safe use in a structure produced by the FSW (Friction Stir Welding) of Mg alloys, this paper proposes a method for determining the range of welding conditions that can ensure a particular joint defect size limit. The welding parameters used are the rotation speed of the tool ω and the welding speed v. Generally, a welding condition is selected using only the fatigue strength as an index. However, ensuring the fatigue strength in a particular welding condition does not insure the strength and reliability of a welded part, because actual welding is not typically carried out in a particular welding condition. Therefore, a range of conditions that can ensure a particular fatigue strength is required. Moreover, we also consider parameters that represent the factors that decrease fatigue strength, namely, √area, HV, and R, because the welding conditions that can ensure a particular fatigue strength are determined by an evaluation of these factors, as well. Therefore, in this study, a method for determining a range of welding conditions that can ensure a welding defect size limit is proposed. Furthermore, FSW welding tests were carried out and the validity of the proposed method was evaluated. X-ray transmission measurements were carried out to measure the welding defect size obtained using the method. Then, the prediction of the maximum welding defect size was carried out for a welding length of 25 [m], which is representative of body of a the Shinkansen rolling stock car.

    Ductile to brittle transition in magnesium alloy with a crack
    We evaluated the strength of a cast non-combustible magnesium alloy that is intended for use in automobile engines. This alloy contains thin sheet-like oxides because of its production process. The size of these thin sheet-like oxides varies, and this means that the temperature dependency of the strength characteristics of the alloy cannot be determined by a tensile test alone. Initially, specimens of the alloy having an artificial pre-crack of 5 [mm] to simulate the sheet-like oxides were subject to tensile testing. The testing was carried out at room temperature (23 [°C]), 150 [°C], 200 [°C] and 250 [°C]. 250 [°C] is the temperature of the environment in which the alloy will be used in automobile engines. All the fractures propagated from the artificial pre-crack and the alloy exhibited its maximum strength at 150 [°C]. To investigate the temperature dependency of the fracture mechanism, a scanning electron microscope (SEM) was used to observe the region near the tip of the pre-crack on the fracture surface of the specimens tested at room temperature and at 250 [°C]. On the fracture surface of the specimen tested at 250 [°C], some dimples were observed over some of the surface near the tip of the artificial pre-crack; however, the fracture surface of the specimen tested at room temperature showed brittle fracture surface morphology over the entire area. For the magnesium alloy, the critical resolved shear stress for non-basal slip, which is a characteristic of a hexagonal close-packed metal, is dependent on temperature. Therefore, ductile to brittle transition was considered to be occurred at a temperature between room temperature and 250 [°C]. Mechanical restraint is also considered to be affected the ductile to brittle transition.

    Determination of effective stress intensity factor range of mode ii fatigue crack propagation using improved experimental method
    Many cases of rolling contact fatigue failure, such as those that occur in railway rails, rolling bearings, and gears, are due to repeated high shear load. In order to prevent such fatigue failures, the resistance of a material against to repeated high shear load must be determined. The fatigue crack growth rate is dependent on the stress intensity factor range of Mode II ΔK II. However, Mode II crack propagation characteristics vary according to the method by which they are determined. We improved the experimental method proposed by Murakami and measured the effective stress intensity factor range of Mode II AK IIeff. Changes to the jigs and specimen were made and the experimental method was such that the ideal mechanical model was expected to be approached. Furthermore, to measure the ΔKIIeff, several strain gauges were applied to the specimen around the crack tip. Using the improved method, some ΔK IIeff values during the Mode II fatigue crack propagation tests can be measured.

    Measurement of effective stress intensity factor range of mode II fatigue crack growth using hysteresis loop
    A method was proposed for measuring the effective stress intensity factor ranges of Mode II fatigue crack growth by using the hysteresis loop for a specimen's surface strain. Many cases of rolling contact fatigue failure, such as those that occur in railway rails, bearings and gears are due to repeated high shear loads. In order to prevent such fatigue failures, the resistance of a material to repeated high shear loads must be determined. The fatigue crack growth characteristics are dependent on the Mode II stress intensity factor range. However, conventionally measured Mode II fatigue crack growth characteristics vary according to the measurement methods. Therefore, the authors improved the experimental measurement method proposed by Murakami, and proposed a way to measure the Mode II effective stress intensity factor range. Improvements to the jigs and specimen were made based on the ideal mechanical model of the experimental method. Furthermore, to measure the Mode II fatigue crack growth behavior, strain gauges were applied to the specimen and the hysteresis loop of the strain was measured with high accuracy by using a newly developed subtraction circuit.

    Tensile-and fatigue-properties of low alloy steel JIS-SCM435 and carbon steel JIS-SM490B in 115 MPA hydrogen gas
    Copyright © 2014 by ASME. Slow strain rate tests using smooth specimens of two types of steels, low alloy steel JIS-SCM435 and carbon steel JIS-SM490B, were carried out in nitrogen gas and hydrogen gas under a pressure of 115 MPa at three different temperatures: 233 K, room temperature and 393 K. In nitrogen gas, these steels exhibited the so-called cup-and-cone fracture at every temperature. On the other hand, in hydrogen gas, in both steels a number of cracks initiated on the specimen surface and coalesced with each other at every temperature, which led to a marked reduction in ductility. Nonetheless, even in hydrogen gas, JIS-SCM435 exhibited a certain reduction of area after the stress-displacement curve reached the tensile strength (TS), whereas JIS-SM490B exhibited little, if any, necking in hydrogen gas. In addition, tension-compression fatigue testing at room temperature revealed that in both steels there was no noticeable difference between the fatigue strengths in air and 115MPa hydrogen gas, especially in a relatively long life regime. Considering that there was little or no hydrogen-induced degradation in either TS or fatigue strength in JIS-SCM435, it is suggested that JIS-SCM435 is eligible for fatigue limit design on the basis of a safety factor (i.e. TS divided by the allowable design stress) for mechanical components used in hydrogen gas up to 115 MPa.

    Fatigue-life and leak-before-break assessments of CR-MO steel pressure vessels with high-pressure gaseous hydrogen
    Copyright © 2014 by ASME. Pressure cycle tests were performed on two types of Cr-Mo steel pressure vessels with inner diameters of 306 mm and 210 mm and notches machined on their inside under hydrogen-gas pressures, varied between 0.6 and 45 MPa at room temperature. One of the Cr-Mo steels had a fine microstructure with tensile strength of 828 MPa, while the other had a coarse microstructure with tensile strength of 947 MPa. Fatigue-crack growth (FCG) and fracture-toughness tests of the Cr-Mo steels were also carried out in gaseous hydrogen. The Cr-Mo steels showed accelerated FCG rates in gaseous hydrogen compared to ambient air with an upper bound corresponding to an approximately 30-times higher FCG rate. Furthermore, in gaseous hydrogen, the fracture toughness of the Cr-Mo steel with coarse microstructure was significantly smaller than that of the steel with fine microstructure. Four pressure vessels were tested; then, all of the pressure vessels failed by leak-before-break (LBB). Based on the fracture-mechanics approach, the LBB failure of one pressure vessel could not be estimated by using the fracture toughness in gaseous hydrogen. The fatigue lives could be estimated by using the upper bound of the accelerated FCG rates in gaseous hydrogen.

    This study aims at understanding the change of the hydrogen embrittlement mechanism with respect to hydrogen content of a precipitation-strengthened Fe–Ni–Cr-based steel. Hydrogen was electrochemically introduced with different current densities. The hydrogen-charging deteriorated crack initiation and propagation resistances as well as the crack tip blunting capability. Further, with increasing hydrogen content, the primary cracking sites changed from coarse carbides to slip bands, and then to grain boundaries. Moreover, because the crack initiation probability increased and the resistance to trans-granular crack propagation decreased with hydrogen content, the crack coalescence associated with slip localization occurred more frequently.

    © 2018 Elsevier Ltd Fatigue tests and hardness tests were conducted in order to clarify the effects of the shapes of small flaws and damage caused by a focused ion beam (FIB) on the fatigue strength characteristics of annealed medium‑carbon steel. The notch root radius of the flaw at the branch point dominates the type of the fatigue limit and was found to be approximately 50 μm, a value that was significantly smaller than the 500 μm of two-dimensional notches in steel. The effect of the FIB-damaged layer on fatigue crack initiation from the FIB-milled notch in the steel was negligible. Moreover, the present study indicated that the effect of the FIB-damaged layer on the fatigue crack initiation at the FIB-milled notch could be evaluated simply by using a hardness test for the other materials and FIB conditions.

    Influence of shear-affected-zone due to punching on tensile characteristics of steel plate
    © 2018 The Authors. In punched steel plate, "punched specimen" from here onwards, the region near the edge of the punched hole is called the shear-affected-zone (SAZ), where tensile characteristics are compromised due to the punching process. However, the specific characteristics and influence on the tensile characteristics of the SAZ are unknown. Therefore, it is difficult to predict the effects of punching on the specimen. Here, we evaluated two kinds of specimens: punched and "honed." The hole of the honed specimen is formed by drilling and polishing, thus there is no SAZ on the honed specimens. In these specimens, we focused on the initiation and propagation of cracks under tensile loading and set the following objectives: (1) Determine whether any special events occur in the fracture mechanism of the punched vs honed specimens under tensile loading. (2) Find the reasons for any special events that occur. In our investigation, a punched specimen showed brittle fracture even within the static range of the strain rate. By failure surface observation of the punched specimens, we found that under tensile loading, cracks caused by the shear stress aligned with the tensile direction initiate in the SAZ. These cracks are the origin of the final fracture of the punched specimen. We assumed that whether the break is a ductile failure or brittle fracture depends on whether the crack tip becomes blunt. The differences in the fracture behaviors are investigated via detailed fracture surface observation.

    Re-examination of fatigue crack propagation mechanism under cyclic Mode II loading
    © 2018 The Authors. The essence of rolling contact fatigue is the so-called "Mode II fatigue crack propagation." However, its understanding has not progressed as much as that of Mode I. We think that this cause is the name: "Mode II fatigue crack propagation." Originally, Modes I and II represented the loading modes for still cracks in fracture mechanics, and not the fatigue crack propagation mechanism. There are many cases where the knowledge of fatigue crack propagation under Mode I loading is applied to that under Mode II loading without consideration. Moreover, in the rolling contact fatigue region where the fatigue crack propagates under Mode II loading, a large plastic deformation is caused by the rolling contact load. Therefore, it is necessary for the test method to reproduce the effects of an actual machine to test materials that exhibit large plastic deformation. Therefore, in this study, we aim to classify the fatigue crack propagation phenomena, regardless of Mode I and II loadings, and re-examine the mechanisms. To that end, we developed a novel test method that enables pure Mode II loading. We used a micro-thin film disc as a specimen, making it possible to cut out and test a part subjected to a large plastic deformation from the actual machine. By observations of the crystallographic structure before the fatigue test and the successive observation of fatigue crack propagation behavior, we propose a crack propagation mechanism, namely, damage accumulation type fatigue crack propagation under Mode II loading, which is different from the opening type fatigue crack propagation.

    A case study of a cooling pipe for a pre-cooler used in a 70-MPa hydrogen station
    Copyright © 2017 ASME. A case study was conducted on the cooling pipe of a pre-cooler which had been used in a 70-MPa hydrogen station demonstration project. The cooling pipe consisted of a main pipe, a mechanical joint pipe and a mechanical joint. The main and mechanical joint pipes had been joined using TIG welding. Through chemical composition analysis, microstructure observation and Vickers hardness measurement, it was revealed that the main and mechanical joint pipes had been manufactured from SUS316L and that 316L was the filler metal used for TIG welding. Round-bar specimens were machined out of the main pipe in order to investigate the tensile properties of the base metal. On the other hand, both round-bar specimen without reinforcement and square-bar specimens with reinforcement were fabricated from the weld-joint. Using the three types of specimens, slow strain rate tensile tests were performed in 0.1 MPa nitrogen gas and in 115 MPa hydrogen gas at a temperature of -40 °C. Reduction of area (RA), φ, for the round base-metal specimen, the round weld-joint specimen and the square weldjoint specimen were respectively, 83.5 %, 71.3 % and 81.4 % in nitrogen gas, whereas the related values in hydrogen gas were 60.1 %, 61.3 % and 40.1 %. In other words, the RA for the three types of specimens was smaller in hydrogen gas than in nitrogen gas. Dimples were formed on the fracture surfaces of the three specimen types in nitrogen gas, whereas both dimples and quasi-cleavages were formed in hydrogen gas.

    The fracture toughness, J_<Ic>, of SCM435 was investigated in 115 MPa hydrogen gas, 0.7 MPa hydrogen gas and air at room temperature. J_<Ic>ig tests were conducted in accordance with the ASTM E1820. J_<Ic>ig in 115 MPa hydrogen gas was much smaller than in 0.7 MPa hydrogen gas and air. In air, a stretched zone was formed at the tip of the fatigue pre-crack, followed by dimples. In hydrogen gas, quasi-cleavage instead of stretched zone and dimples were formed at the pre-crack tip. The fracture toughness test shown in 0.7 MPa hydrogen gas is the same as that shown in a fatigue crack growth test in 0.7 MPa hydrogen gas at a number of cycles of n = 1 and stress ratio of R = 0; and thus J_<Ic>ig in hydrogen gas is not the real fracture toughness.

    In order to clarify an influence of hydrogen on the fatigue crack propagation in ultra-low frequency region, we investigated the frequency dependence of the crack propagation rate of S10C in hydrogen and nitrogen atmosphere. In the hydrogen atmosphere, crack propagation rate decreased with decrease in frequency. In particular, the reduction in crack propagation rate was markedly low in the ultra-low frequency (0.001 Hz). However, crack propagation rate in the nitrogen atmosphere also decreased in the ultra-low frequency region. Hence, we concluded that the decrease in crack propagation rate was concluded to stem from carbon diffusion as well as hydrogen diffusion.

    Tensile-and fatigue-properties of low alloy steel JIS-SCM435 and carbon steel JIS-SM490B in 115 MPA hydrogen gas
    Copyright © 2014 by ASME. Slow strain rate tests using smooth specimens of two types of steels, low alloy steel JIS-SCM435 and carbon steel JIS-SM490B, were carried out in nitrogen gas and hydrogen gas under a pressure of 115 MPa at three different temperatures: 233 K, room temperature and 393 K. In nitrogen gas, these steels exhibited the so-called cup-and-cone fracture at every temperature. On the other hand, in hydrogen gas, in both steels a number of cracks initiated on the specimen surface and coalesced with each other at every temperature, which led to a marked reduction in ductility. Nonetheless, even in hydrogen gas, JIS-SCM435 exhibited a certain reduction of area after the stress-displacement curve reached the tensile strength (TS), whereas JIS-SM490B exhibited little, if any, necking in hydrogen gas. In addition, tension-compression fatigue testing at room temperature revealed that in both steels there was no noticeable difference between the fatigue strengths in air and 115MPa hydrogen gas, especially in a relatively long life regime. Considering that there was little or no hydrogen-induced degradation in either TS or fatigue strength in JIS-SCM435, it is suggested that JIS-SCM435 is eligible for fatigue limit design on the basis of a safety factor (i.e. TS divided by the allowable design stress) for mechanical components used in hydrogen gas up to 115 MPa.

    The effect of hydrogen on the strength of metals is known as hydrogen embrittlement, which affects the structural integrity of a hydrogen energy system. The effect of hydrogen at a specimen with a crack is stronger than a smooth specimen. With our simulation's result, it is generally recognized that hydrogen atoms near a crack tip play an important role in the hydrogen embrittlement. This research purpose is the reproduction of the localized plastic zone at the tip of a crack. Due to the purpose, we proposed a novel nonlinear constitutive equation. In this equation, we used a hypothesis that the hydrogen absorbed in the metal affects the yield stress of the metal. A simulation with the proposed equation was performed and from the result, we observed increasing of dislocation at the tip of a crack but we could not observe the localized plastic zone at the tip. From these simulation results, we proposed a hydrogen embrittlement mechanism .

    A TWIP (Twinning Induced Plasticity) steel is an austenitic steel which contains about 30% Mn , 3% Si and 3% Al, and have attracted much attention for their excellent mechanical properties such as its strength and strain hardening. Fatigue life is an important property of the material. In the study, to find the relationship between the strain hardening and the fatigue life for the Fe-30Mn-3Si-3Al TWIP alloy, analyses of the strain hardening under different applied strain were performed. For this, tension and compression strain controlled low-cycle fatigue tests were carried out in order to obtain the relationship between the strain hardening and the fatigue life. From the test, the stress-strain curve and the stress which changes as increasing the number of cycles were obseved. Briefly, the results indicated the state of hardening rate under Δε = 2.0% was higher than Δε = 1.0% conditions. In this paper we tried to find the work-hardening effect under the low cycle fatigue loading.

    A small artificial hole is regarded as a pre-crack and square root area parameter is considered as one of the most important parameter for the fatigue limit of materials which contain small defects. In this study, introducing a sharp notch by using focused ion beam (FIB) or a small artificial hole which have the same area on the quenched and tempered 0.45% carbon steel specimen, we carried out these specimens fatigue tests and we investigated the difference of the two defect shape in the hard material. From the fatigue tests, we obtained two important results. First, the fatigue limit of the specimen with the small artificial hole was higher than the specimen with the FIBed notch. Second, fatigue crack initiation and propagation behavior was different between the two types of the specimens. Usually, there are no differences for annealed steel in the two defect shapes. Therefore, the hardness may affect the fatigue crack behavior of the two defect shapes.

    Recently, polymer materials have increasingly used in many industries due to their unique properties, such as chemical corrosion resistance and its lightness. Despite the investigations which are being carried out on the fatigue phenomena of epoxy resin with various kinds of fibre, the epoxy does not seem to have been fully studied. Moreover, there is lack of understanding about the fatigue behavior and its mechanism. In cyclic bending fatigue tests, on the other hand, the resin are easily fractured even though the stresses are below the critical values. The objective of this study is to analyze the fatigue crack growth behavior of epoxy resin (bisphenol-A-epichlorohydrin type epoxy resin) during mechanical repeated loads. The rotating bending fatigue test was carried out in order to analyze the fatigue crack propagation. A notch was introduced on the specimen, therefore a crack propagates and cause the final fracture of the specimen. In this paper we tried to find the fatigue crack behavior.

    This paper is to propose a method to predict the fatigue limit of the material having a defect of any shape. The 5056 aluminum alloy with Mg added has a fatigue limit, but in the case of specimens with Micro-Hole or smooth specimens, the fatigue crack is not initiated in the fatigue limit. Under these circumstances, the fatigue limit is equal to the fatigue crack initiation limit. Therefore, the following two experiments were carried out to elucidate the material property of5056 aluminum alloy adding Mg: (1) Fatigue test of notched specimens for the prediction of the fatigue limit in the area where the fatigue limit is equal to the fatigue crack initiation limit. (2) Fatigue test of Pre-Cracked specimens when a defect has sufficient stress concentration to initiate the non-propagating crack. From (1) and (2), we propose a method of predicting the fatigue limit of materials having a defect of any shape with a minimum number of fatigue tests. Furthermore, to test this method, we examined whether theoretical values and test results are equal for some specimens with Micro-Hole.

    An evaluatuation for threshold stress intensity factor range under a stress controlled condition, using effective threshold stress intensity factor range, was proposed. Threshold stress intensity factor range was evaluated by analyses of plasticity-induced crack closure for two types of crack size:a small crack and a long crack. Plasticity-induced crack closure was analyzed for two dimensional crack in plane stress. Besides, theoretical examinations were performed in order to explain the mechanism that the fatigue limit of high hardness steel decrease with a rise of hardness. Relationship between threshold stress intensity factor range and pre-crack length which was evaluated by analysis of plasticity-induced crack agreed with experimental results qualitatively. Dependency of yield stress was different between a small crack and a long crack. The threshold stress intensity factor range of a long crack decrease with a rise of yield stress. This result could be helpful to reveal the mechanism that the fatigue limit decrease with a rise of hardness in high hardness.

    In order to clarify the transition of the coefficient in ASTM standard equation by the degree of work hardening, elastic-plastic finite element method analysis in which stress-strain curve was approximated by two straight line of Young's modulus E and tangential modulus E_twas carried out. By dividing stress by yield stress and strain by yield strain, various stress-strain curves could be expressed only by using the value of E_t/E. Based on the non-linear crack mechanics, the loading stress when equivalent plastic strain at node point of a crack tip became a constant value was obtained as an analysis solution. Imitating the normalized arrangement manner of numerical solution in Dugdale model in which similarity rule is effective under continuum mechanics, dimensionless quantities relevant to stress intensity factor and crack size were defined. Element size dependency in analytical solution was eliminated and transition in coefficient of small scale yielding condition equation against the value of E_t/E. was proposed. When normalized crack size a/l_0=200 and ratio of tangential modulus to Young's modulus (E_t/E) is 0.2, the coefficient of small scale yielding was 2.5 which is equal to ASTM standard condition equation.

    In order to clarify the small scale yielding condition in magnesium alloy, FEM analysis of the R-curve whose shape is considered to be the material characteristic shape was carried out. As an object material, magnesium alloy AZX312 was used. From the FEM analysis results, the shape of the R-curve of its first step when an initial crack size α= 200 μm is obviously different from those of α= 900μm and α= 2000μm. It is considered that the transition crack size from the small scale yielding to the large scale yielding may be between 200 μm and 900 μm. However, the threshold crack size given by the ASTM standard E399 is much larger than 900μm. The ASTM standard is based on experimental results of many materials, however, the standard does not consider the difference of Young's modulus of each materials. So, in magnesium alloy whose Young's modulus is low, the ASTM standard is considered to be not effective.

    Microscopic fatigue crack behavior in precipitation strengthening stainless steel A286
    In order to clarify the fundamental fatigue strength characteristic of precipitation strengthening type stainless steel: A286, fatigue tests were performed. In the fatigue test, the authors paid attention to the behavior of microscopic fatigue cracks in order to make clear fatigue strength properties more than those with usual fatigue tests. As a result of the fatigue test, the fatigue strength characteristic of A286 became clear as shown below. The crack of a size according to a crystal grain diameter is easy to initiate and propagate by Mode II. Many cracks initiate and propagate even if the stress is around the fatigue limit and the fatigue crack cannot stop, then the cracks coalesce and it becomes longer, and finally results in a failure. This is the reason why the fatigue failures occur even after 10 7 cycles. © 2011 The Japan Society of Mechanical Engineers.

    It is difficult to evaluate the strength of material which has defects, because the strength differs variously by the stress concentration, the defects size and the temperature. In this study, the evaluation method for material with defects was studied. As an example, non-combustible magnesium alloys to which some silicon was added were applied. At first, observation of the fracture surfaces of specimens with a small hole was carried out. Although some dimple can be observed near the hole on the fracture surface of specimen tested in 250℃, no dimple was in room temperature. By the observation it was clarified that the fracture mode near the defect can be divided into two modes, i.e. brittle fracture and ductile fracture. In addition, by tensile tests of specimens with a notch, change of the fracture mode was also observed by degree in stress concentration. Understanding the two problems, i.e. degree in stress concentration of the defects in material and relationship between the defects size and strength are future tasks.

    In order to systemize the analysis method of fatigue crack initiation origin (fatigue failure maximum weak part), fatigue failure maximum weak part and the relationship to material texture were analyzed. Pearlitic steel smooth material was used for the material made into the example. First, a mechanical engineer's focus and technology were used, specification of a fatigue failure maximum weak part in pearlitic steel smooth material was performed, and relation between material texture and a fatigue failure maximum weak part was clarified. Then, analysis to material texture was carried out using the knowledge and analysis technology of crystallography of a metallurgist. A fatigue test and analysis showed that a flat face existed at the fatigue crack initiation origin of pearlitic steel smooth material. In addition, as a result of the analysis of a flat face, the formation mechanism of fatigue crack initiation origin (flat face) was able to be clarified, and systematization of analysis was able to be attained.

    In order to clarify the relationship between fatigue strength and hardness of precipitation strengthening type stainless steel: A286, tensile tests, fatigue tests and Vickers hardness tests were performed. As a result of the tests, A286 steel have high tensile strength as well as low fatigue strength. Then, from the result of hardness test, there is large variability in hardness distribution of A286 steel. High hard zone and low hard zone were found in a specimen of A286 steel. The hardness of the zone in which many cracks initiated, is lower than the zone in which few cracks initiated. It is considered that high tensile strength is based on average both high hardness zone and low hardness zone when tensile test, and low fatigue strength was caused by the fatigue cracks which are easy to initiate and propagate in low hardness zone. Therefore, this is the reason why the fatigue strength ratio of A286 steel is lower than most steel.

    Evaluation method of the fatigue limit of material with small crack under tensile mean stress, using the stress ratio parameter and effective threshold stress intensity factor range (ΔK_<eff,th>), was proposed. By this method, the fatigue limit can be evaluated in high mean stress area and low mean stress area separately. In order to define the crack size, which is applied to the evaluation method, the variation of the small crack area affected by stress ratio was shown, using the relationship between threshold stress intensity factor range (ΔK_<th>) and the projected area of crack size in the direction of the load (√<area>). The higher stress ratio is, the smaller the upper crack size of small crack area is considered to be. Taking non-combustible Mg alloy as an example, tension-compression fatigue tests were carried out. Using the results of the tests, the validity of the proposed evaluation method was examined.

    Many rolling contact fatigue failures, such as those that occur in railway rails, rolling bearings and gears, are due to the high repeated shear load. In order to prevent such fatigue a failure, the resistance of the material against such a load must be determined. The fatigue crack growth rate is dependent on the Mode II stress intensity factor range ΔK_<II>. However, the Mode II crack propagation characteristic varies according to different experiment methods. Therefore, in this study, we measured the effective Mode II stress intensity factor range ΔK_<IIeff>. As it is difficult to carry out the Mode II fatigue crack propagation in the laboratory, this test was carried out using a bending load in this study. This bending load was applied to the tips of a double cantilever specimen and the Mode II fatigue crack propagation could be carried out between the two cantilevers. Furthermore, in order to measure the ΔK_<IIeff>, several strain gauges were applied to the specimen around the crack tip. Using this technique, some ΔK_<IIeff> value during the Mode II fatigue crack propagation tests will be reported.

    Strength evaluation of alumina's spray coating (5th report, consideration of the strength in sprayed structure for thermal stress)
    In this study fracture probability at thermal stress distribution is calculated with the dangerous volume quantification method that was proposed in the former report Fracture stress calculation by thermal stress is based on finite element method with fracture temperature and aluminum creep properties. The fracture strengths predicted with the proposed method are appropriate to experimental results obtained by heat tests. The calculated dangerous volume intended for 90% of product in alumina&#039;s spray coating on aluminum layer is part of 96% or more of maximum stress. Therefore the dangerous volume calculation in thermal stress distribution is enough to think experienced dangerous volume calculation method that dangerous volume is volume of 90% or more of maximum stress. And it is shown that fracture origin is located in the dangerous volume calculated with this study method and fracture strengths predicted with fracture origin size is almost equal to the fracture strengths predicted with this study.

    Strength evaluation of alumina's spray coating (4th report, consideration of spray structure strength for mechanical stress)
    In this study, in order to calculate dangerous volume at various stress distribution, the dangerous volume quantification method is proposed. And in order to predict stress distribution of spray coating, an easy calculation method of residual stress distribution based on the first report is proposed. The calculated dangerous volume in alumina&#039;s spray coating on titanium layer is different from alumina&#039;s spray oating single layer. The difference is based on stress distribution in alumina&#039;s spray coating. The fracture strengths predicted with the proposed method and the third report are appropriate to experimental results obtained by 4-point bending tests. Therefore dangerous volume calculation in thermal stress distribution that is different from mechanical stress distribution also become possible.

    Analysis of small spalling mechanism on hot rolling mill roll surface
    In order to analyze the small spalling mechanism on the surface of the hot rolling mill high speed steel roll, an actual hot rolling mill roll was investigated, and the thermal cycle and Mode II fatigue crack growth tests, which reflect the results of the investigation, were carried out. From the investigation of the actual hot rolling mill roll, it was proven that the small spalling was generated by heat crack initiation by thermal cycling and Mode II fatigue crack growth. The crack due to the thermal cycling was initiated in the oxide area. Estimation of the small spalling hot rolling mill roll life on the roll surface became possible based on the relationship between the crack growth rate da/dN and threshold Mode II stress intensity factor range ΔKIIth, and it was clarified that the life of the Mode II fatigue crack growth was longer than that of the crack initiation life by thermal cycling.

    Fatigue strength characteristics of non-combustible Mg alloy (2nd report, effect of mean stress on fatigue strength)
    Rotating bending tests and tension-compression fatigue tests on non-combustible magnesium alloy were carried out to investigate effect of mean stress on fatigue strength at N=107 The ignition point of non-combustible magnesium alloys is about 300 K higher than that of normal magnesium alloys because of calcium addition. It was clarified as follows. (1) In the range of σm MPa, fatigue strength at N=107 of small hole specimens was about 30-150% higher than that of small crack specimens. (2) In the range of σm>100MPa, fatigue strength at N=107 of small hole specimens decreased because of static cracks initiating around small hole at the first loading. (3) In the range of σmax<σ0.2, fatigue strength at N=10 7 of smooth specimens was estimated using modified Goodman diagram.

    SIMS analysis of hydride in commercially pure titanium
    Commercially pure titanium (CP-Ti) usually contains a few tens of ppm hydrogen. In order to clarify the fatigue behavior of CP-Ti, it is important to know the distribution of such hydrogen. In this study the distribution of hydrogen formed as hydride was analyzed by secondary ion mass spectrometry (SIMS). The hydrides could be detected interior the grain and at the grain boundaries. On the basis of the results, the points to be paid attention for the investigation of fatigue strength are discussed.

    OS4-5-5 Fatigue Strength Characteristics of Non-combustible Mg Alloy
    The ignition point of non-combustible Mg alloy is about 300K higher than that of normal magnesium alloy. It is expected that the non-combustible Mg alloy is used in substitution for Al alloy for structures. In this paper, the fundamentals, those are a notch effect, and a long or small crack effect on fatigue strength of a non-combustible Mg alloy, are investigated. Moreover, the fatigue strength characteristics of the non-combustible Mg alloy are compared with that of Al alloy to clarify differences of fatigue strength characteristics between Mg alloy and Al alloy.
