    田中 將己氏の研究は、建造物や運輸機器、原子炉などに使用される構造材料の破壊起点であるミクロな亀裂先端の挙動を、高分解能電子顕微鏡を用いて原子尺度で解明しようとするものです。
    金属などの構造材料が外部から力を受けて変形し、限界に達すると原子結合が切断され亀裂が発生します。この亀裂の先端が進展する事によって破壊に至ります。破壊は必ずしも一気には進まず、亀裂先端近傍での応力緩和により一定の遅れを示します。この緩和の度合いが、材料の強度を大きく左右し、構造物の最終的な強度をも決めると言っても過言でありません。しかし、これほど重要な課題であるにもかかわらず亀裂先端における応力緩和機構は今日に至るまで完全には解明されておりません。亀裂先端の挙動に関わる領域は、その周囲を含めても原子尺度で測れる程度の広がりに留まるので、問題解決には原子尺度での構造情報が必要です。しかしながら、亀裂先端近傍の格子転位を媒介にした歪み場を、高分解能電子顕微鏡によって原子レベルで構造解析はこれまで困難でした。このことが問題解決を妨げる大きな要因でした。
    田中将己氏は、計算機との連携による電子顕微鏡の応用技術の向上により、これまで困難とされてきた格子転位を含む歪み場の高分解能電子顕微鏡による原子尺度の評価が可能になってきたことを踏まえて、亀裂先端の歪み場を原子尺度で実験的に解析して、材料物理学、材料強度学における長年の懸案である、亀裂先端における応力緩和機構を、これまで培われてきた弾性論との整合性をふくめ、解明する事を目指しており、その成果が大いに注目されます。

  • Strain Rate Dependence of Slip Persistence in TiZrNbHfTa Investigated with Microcantilever Bending Tests

    Tanaka Masaki, Yamasaki Shigeto, Morikawa Tatsuya

    <p>The strain-rate dependence of slip persistence in TiZrNbHfTa was investigated using microcantilever bending tests instead of conventional single-crystal tensile tests. These tests were performed using micrometre-sized cantilevers fabricated within a grain of the polycrystalline material, and the ψ–χ relationship was obtained in detail. Bending tests were conducted in two strain rates to determine the ψ–χ relationship. The results showed that the slip plane macroscopically persisted on the {112} plane in the high-strain-rate test, while in the low-strain-rate test, the apparent slip plane roughly coincided with the plane where the maximum shear stress was applied. Detailed tracing of the slip bands, using atomic force microscopy, on the specimen surface showed that the slip plane was microscopically persisted on the {112} plane in high-strain-rate tests, while in low-strain-rate tests, the slip plane often cross-slipped between the {112} and {110} planes.</p>

  • Effect of Local Deformation Microstructure on Ductile Fracture Behavior of Ferrite-Bainite Duplex Steel

    <p>Microscopic deformation and fracture behavior of a ferrite-bainite dual phase steel was investigated by the micro-grid method and FE analysis to understand the inherent conditions of plastic instability and ductile fracture. The micro-grid method, which the microscopic strain is measured by the displacement of grids with 500 nm intervals drawn on the specimen surface, clearly revealed that the shear deformation along the lath structure in the bainite phase was seen before reaching the maximum loading point. Then, voids were observed in the ferrite phase adjacent to the ferrite/bainite boundary, where showing higher strain concentration. From the FE analysis with the model simulating actual ferrite-bainite microstructure, stress distribution was seen in the bainite phase, and high stressed regions could cause the shear deformation of the bainite phase. The local shear deformation in the bainite phase decreased strain hardenability and triggered the macroscopic plastic instability. It is considered that the macroscopic plastic instability accelerates the strain localization, and promotes the void nucleation and growth. Ductile fracture path was also visualized by the micro-grids in the ferrite phase along the shear deformation bands which is connecting the high strain regions. Development of shear deformation bands inside the ferrite phase was well simulated with the FE analysis, same as the development of high stressed region in the bainite phase in the early stage. It can be stated, therefore, that plastic instability and ductile fracture of dual phase steel is a structure dependent phenomenon which is strongly controlled by the morphologies of each constituent phases.</p>

    <p>Microscopic stress-strain curves were obtained by applying stress measurements using the HR-EBSD method and strain measurements using the DIC method to the same field of view in SEM <i>in-situ</i> tensile tests. From the analysis of these microscopic stress-strain curves, yield stress map and work hardening rate map were successfully produced. The relationship between these mechanical property value maps and the microstructure is investigated. The yield stress maps confirm the tendency of the local yield stress to show different values for different grains, but the Schmid factor alone cannot explain the magnitude of the yield stress. When adjacent grains with significantly different Schmid factors deformed cooperatively, the yield stress is found to increase as a result of stress partitioning. Localized regions of extreme work hardening rates were observed in the work hardening rate maps. These regions were located close to grain boundaries with low <i>m</i>′ values where slip transfer was difficult and an interruption of the slip bands was observed. In addition, the rate of increase of GND density with strain was large in these regions. From these results, it can be understood that the extreme work hardening rates are due to increased back stresses caused by the accumulation of dislocations on low <i>m</i>′ grain boundaries.</p>

A fatigue test was programmed to include displacement holding for only one cycle at several Δ<i>K</i>. We found (1) crack tip strain evolved during the displacement holding, (2) the displacement holding increased fatigue striation spacing, and (3) the strain increment during the displacement holding was linearly correlated with spacing of the displacement-holding-extended striations. These facts indicate that the dwell loading assisted crack opening, which accelerated the crack propagation. Other analyses results and discussion are also presented, in terms of crack propagation mode, crack closure, and dislocation structure.</p><p> </p><p>Mater. Trans. <b>63</b> (2022) 1232-1241に掲載</p>

    A method for obtaining microscopic and localized stress-strain curves is proposed by combining strain measurements using the digital image correlation (DIC) method with stress measurements using high-resolution electron backscattered diffraction (HR-EBSD). A dataset containing 11 steps of stress–strain information in a single subset was created by applying georeferencing to DIC strain maps and HR-EBSD stress maps measured in a deformation-interrupted microstructure. This analysis allowed us to obtain local stress-strain curves and strain energy maps of polycrystalline nickel alloys. A comparison of the stress-strain curves obtained from any subset in the map revealed that these curves show extremely diverse shapes depending on the location in the microstructure.

    <p>Impact tests and tensile tests were conducted between 77 K and 450 K in order to elucidate the temperature dependence of absorbed-impact energy, yield stress, effective shear stress, activation volume, and activation enthalpy. The impact-absorbed energy decreased with decreasing test temperature, however, this alloy did not undergo low-temperature embrittlement although it has a bcc structure. Tensile tests showed changes in both the work-hardening rate and the temperature dependence of yield stress at approximately 150 K. This suggests a change in the mechanism behind the plastic deformation at the temperature. The temperature dependence of the activation enthalpy for dislocation glide suggests that the process of climbing over the Peierls potential (kink-pair nucleation) is the dominant mechanism for the dislocation glide from 150 K to 200 K, while the interaction between a dislocation and solute atoms dominantly controls the dislocation glide above 200 K. Superelasticity appears in stress-strain curves tested below 120 K, suggesting that the yielding is governed by transformation-induced plasticity below 120 K. The enhanced toughness at low temperatures in these alloys is discussed from the viewpoint of dislocation shielding theory.</p>

  • Micromechanical testing for quantitative characterization of apparent slip system: Extinction of persistence of slip in carbon bearing Fe-3% Si

    The effect of carbon on the persistence of the slip in Fe–3 mass% Si was investigated. We applied micro-sized cantilever bending tests to obtain ψ–χ relationships that enable quantitative analysis of the persistence of the slip. It was demonstrated that the result from decarburized specimens using this method is consistent with those obtained in previous studies from bulk-sized tensile test specimens. This novel method eliminates the difficulty of preparing bulk-sized single-crystal specimens for investigating the persistence of the slip. The persistence of the slip weakened in aged specimens containing 0.016 mass% C and disappeared in quenched specimens with the same carbon content, where wavy slip bands were observed. The reason for these changes in the macroscopically apparent slip plane is explained by the assumption that the frequency of nucleating kink-pair in the competitive {110} planes is a function of the resolved shear stress.

    <p>To develop microstructure control concepts for ensuring the toughness of high-strength steel plates, basic research was conducted using ferrite single-phase steels with different amounts of C, and the effects of the states of C were investigated along with those of solute N. In this study, Fe-0.017C (mass%) alloy, wherein the state of C was changed to a solid solution, intragranular cementite, and intergranular cementite, were used for microstructural observation, Charpy testing, and fracture surface investigation. The results reveal that the toughness of the intragranular cementite steel was the best, followed by that of solute C steel and intergranular cementite steel. In intergranular cementite steel with significantly inferior toughness, the coarse intergranular cementite leads to dislocation pile-up, initial crack formation, and macroscopic brittle fracture. The brittle fracture of intragranular cementite steel was caused by the deformation twins. It is thought that the fine intragranular cementite only had a minor effect on the crack initiation and dislocation mobility. Twin was also confirmed at the initiation point of brittle fracture in the solute C steel. Hence, it was deduced that the deterioration of toughness caused by solute C resulted from the promotion of twinning, which replaced the dislocation movements. However, the deterioration of toughness caused by solute C was smaller compared with that caused by solute N, which partly caused intergranular fracture. This is attributed to the suppression of intergranular fracture by the presence of a small amount of solute C.</p>

  • Temperature dependence of the yield stress in TiZrNbHfTa body-centred cubic high-entropy alloy

    Body-centred cubic (bcc) high-entropy alloys exhibit high strength. However, their yield behaviour and controlling mechanisms are still ambiguous. In this study, the temperature dependence of the yield stress, effective stress, activation volume, and activation enthalpy in a polycrystalline bcc refractory high-entropy alloy of TiZrNbHfTa were measured by tensile tests at 77–750 K. At temperatures above 650 K, the temperature dependence of the yield stress disappeared, and serration appeared in stress–strain curves. By extrapolating the effective shear stress to 0 K, the Peierls stress was estimated to be 580 MPa. The value was compared with different crystals using the relationship (τ_p)/(μ) and (h)/(b) , where τ_p is the Peierls stress, μ is the shear modulus, h is the distance between the slip planes, and b is the Burgers vector. The (τ_p)/(μ) value in this study was slightly higher than that of other bcc crystals. The activation enthalpy below 260 K corresponds to that of other bcc crystals with high Peierls potentials, suggesting kink-pair nucleation is the controlling mechanism of the dislocation glide in this temperature range.

    Body-centred cubic (bcc) high-entropy alloys exhibit high strength. However, their yield behaviour and controlling mechanisms are still ambiguous. In this study, the temperature dependence of the yield stress, effective stress, activation volume, and activation enthalpy in a polycrystalline bcc refractory high-entropy alloy of TiZrNbHfTa were measured by tensile tests at 77–750 K. At temperatures above 650 K, the temperature dependence of the yield stress disappeared, and serration appeared in stress–strain curves. By extrapolating the effective shear stress to 0 K, the Peierls stress was estimated to be 580 MPa. The value was compared with different crystals using the relationship [Formula presented] and [Formula presented], where τp is the Peierls stress, μ is the shear modulus, h is the distance between the slip planes, and b is the Burgers vector. The [Formula presented] value in this study was slightly higher than that of other bcc crystals. The activation enthalpy below 260 K corresponds to that of other bcc crystals with high Peierls potentials, suggesting kink-pair nucleation is the controlling mechanism of the dislocation glide in this temperature range. Meanwhile, the activation enthalpy above 260 K deviated from the trendline, indicating the changes in the dislocation glide from the kink-pair nucleation to other one.

    Abstract

    The effect of high-temperature heat treatment during production on the mechanical property of Si wafer, namely yield stress, was studied through tensile tests of Si single crystals at 1123–1373 K, where stress–strain curves were obtained along the $\left[\bar{1}34\right],$$\left[011\right],$$\left[001\right],$ and $\left[\bar{1}11\right]$ directions. The critical resolved shear stress showed a remarkable temperature dependence, and it decreased with increasing test temperature. Below 1348 K, the activation enthalpy determined through strain rate jump tests showed no significant difference between crystals made by the Chokralski and the floating zone methods. This indicated that the solute oxygen does not influence the thermally activated dislocation glides. The activation enthalpy of 4.9 eV for a dislocation glide was much higher than that reported by previous studies (2.2 eV at temperatures below 1100 K), indicating that the thermal activation of dislocation glide is different from kink-pair nucleation. It was found that self-diffusion can assist the dislocation glide at temperatures above 1130 K.

    <p>Effect of crack-tip shielding by dislocations is the most fundamental mechanism governing the fracture toughness of crystalline materials. Brittle-to-ductile transition (BDT) caused by increasing temperature is a general phenomenon observed not only in metals and alloys but also in various crystalline materials such as ionic crystals or semiconductors. The increase of fracture toughness in BDT is closely related to the shielding effect due to dislocations multiplied around a crack-tip. The present paper reviews the fundamental theory of crack-tip shielding and its experimental evidence, and also shows the reason why the nature of interatomic bonding has a remarkable influence on macroscopic fracture toughness, based on the shielding theory.</p><p>Hydrogen embrittlement has attracted much attention in the fields of materials science and mechanical engineering although there still remain many arguments on its mechanism. In this paper, the phenomena being characteristic to hydrogen embrittlement are reviewed, and its mechanism is also discussed from the viewpoint of dislocation shielding.</p>

    <p>In this study, the strain distribution in grains with a preferred orientation in a cold-rolled steel plate was investigated. This was done by measuring the amount of strain in a region of the material using nanoscale fine markers applied by a focused ion beam (FIB). We obtained the crystal orientations and strain distributions in the same region using scanning electron microscopy-electron backscatter diffraction and the markers made by the FIB during rolling to a 60% to 70% thickness reduction. The method revealed the strain distributions in the grains with the major preferred orientations (cube:{100}<001>; <i>α</i>-fiber:{100}<011>, {211}<011>; <i>γ</i>-fiber:{111}<011>, {111}<211>). The average strains that accumulated in the grains with different major preferred orientations during cold-rolling were almost the same at thickness reduction in the range of 60%–70%. However, the strain distribution width of the <i>γ</i>-fiber grains was approximately twice that of grains with other orientations. These results suggest that the deformation inhomogeneity during rolling is more pronounced for <i>γ</i>-fiber-oriented grains than for grains with other preferred orientations.</p>

    <p>In this study, the cleavage fracture of the C14 Fe<sub>2</sub>W Laves phase was investigated by first-principles calculations and crystal orientation analysis using scanning electron microscopy. Trace analysis of the orientations of cleavage planes revealed that cleavage fracture occurred in five types of crystal planes: (0001), {1<span style="text-decoration: overline;">1</span>00}, {11<span style="text-decoration: overline;">2</span>0}, {1<span style="text-decoration: overline;">1</span>01}, and {11<span style="text-decoration: overline;">2</span>2}. Among these fractures, the fracture at (0001) is the most preferable. From, the first-principle calculations of the surface energy for fracture, Young’s modulus, and Poisson’s ratio, the minimum fracture toughness value of 1.62 MPa·m<sup>1/2</sup> was obtained at (0001). The tendency of the calculated fracture toughness to become larger with high indexed planes is almost the same as the frequency of the types of cleavage planes in the trace analysis. It was concluded that the fracture toughness of the C14 Fe<sub>2</sub>W Laves phase is controlled by the surface energy for fracture and Young’s modulus.</p>

    <p>Resistance to Sulfide Stress Cracking (SSC) caused by local hard zones of pipe inner surface has been required in low alloy linepipe steel. In this study, using two samples with different surface hardness, the detailed SSC initiation behavior was clarified by four-point bend (4PB) SSC tests in which immersion time and applied stress were changed in a sour environment containing 0.15 bar hydrogen sulfide (H<sub>2</sub>S) gas. SSC cracks occurred when the applied stress was higher than 90% actual yield strength (AYS) in higher surface hardness samples over 270 HV0.1. From the fracture surface observation of SSC crack sample, it was found that the mechanism gradually shifted from active path corrosion (APC) to hydrogen embrittlement (HE), and that the influence of APC mechanism remained partially in the process of SSC initiation at the tip of corrosion pit or groove. The polarization measurement in the 4PB SSC test showed that the anodic and cathodic reactions (especially cathodic reactions) were activated when the applied stress was 90% AYS or higher. The FEM coupled analysis simulating the stress and strain concentration at the bottom tip of the corrosion groove and the hydrogen diffusion and accumulation was carried out. The principal stress in the tensile direction showed the maximum value at 0.04–0.06 mm away from the tip of the corrosion groove, and the hydrogen accumulation became the maximum. It was analytically found that the SSC crack initiated and propagated with HE mechanism dominated type when the threshold value of about 0.82 ppm is exceeded.</p>

A fatigue test was programmed to include displacement holding for only one cycle at several Δ<i>K</i>. We found (1) crack tip strain evolved during the displacement holding, (2) the displacement holding increased fatigue striation spacing, and (3) the strain increment during the displacement holding was linearly correlated with spacing of the displacement-holding-extended striations. These facts indicate that the dwell loading assisted crack opening, which accelerated the crack propagation. Other analyses results and discussion are also presented, in terms of crack propagation mode, crack closure, and dislocation structure.</p>

    We have investigated the effects of the secondary defects caused by ion implantation on wafer strength. The change in wafer strength with the ion dose has been examined after implanting phosphorus or (BF2)+ ions into wafers with and without heat treatment. Ion implantation defects have been observed using transmission electron microscopy after ion implantation with and without subsequent annealing. The three-point bending tests carried out with the ion implanted samples show that the upper yield stress, which represents wafer strength, gradually decreases with the increasing dose in the case of phosphorus ions and rapidly decreases in the case of (BF2)+ ions due to the formation of secondary defects. In addition, the strength of the wafers with a low oxygen concentration is lower than that of the wafers with a high oxygen concentration. However, the rate of decrease in wafer strength with increasing ion dose is not affected by the oxygen concentration; it only depended on the implanted element.

It was found that the fatigue crack growth rate in stage IIb was temperature independent at temperatures above 300 K. EBSD maps beside the fatigue crack showed that prismatic slips with 〈a〉 dislocations were dominantly activated during the fatigue crack growth. The reason why the prismatic slips were dominantly activated is discussed with numerical crystal plasticity analysis. It was shown that the local strain rate at the notch tip was higher than the macroscopic strain rate, which leads to the suppression of non-prismatic slips at the fatigue crack tip.</p>

A trace analysis of the slip band suggested that the crystal rotation in different directions was caused by the activation of different slip systems in each region. The distribution of the equivalent plastic strain from a 60% to 70% reduction owing to a grain subdivision was examined and compared with the change in crystallographic orientation, suggesting that non-uniform slippage deviating from the Taylor model occurred in the regions where a significant orientation change occurred.</p><p>Furthermore, the strain distribution measured by the marker showed that tensile deformation caused by rolling tended to be suppressed compared to compressive deformation near the grain boundaries inclined toward the rolling direction. These results suggest that the local crystal rotation inside the grain, which leads to a grain subdivision during rolling, is caused by a deviation of the strain tensor inside the grain from the ideal rolling state.</p>

    <p>To develop microstructure control concepts for ensuring the toughness of high-strength steel plates, basic research was conducted using ferrite single-phase steels with different amounts of C, and the effects of the states of C were investigated along with those of solute N. In this study, Fe-0.017C (mass%) alloy, wherein the state of C was changed to a solid solution, intragranular cementite, and intergranular cementite, were used for microstructural observation, Charpy testing, and fracture surface investigation. The results reveal that the toughness of the intragranular cementite steel was the best, followed by that of solute C steel and intergranular cementite steel. In intergranular cementite steel with significantly inferior toughness, the coarse intergranular cementite leads to dislocation pile-up, initial crack formation, and macroscopic brittle fracture. The brittle fracture of intragranular cementite steel was caused by the deformation twins. It is thought that the fine intragranular cementite only had a minor effect on the crack initiation and dislocation mobility. Twin was also confirmed at the initiation point of brittle fracture in the solute C steel. Hence, it was deduced that the deterioration of toughness caused by solute C resulted from the promotion of twinning, which replaced the dislocation movements. However, the deterioration of toughness caused by solute C was smaller compared with that caused by solute N, which partly caused intergranular fracture. This is attributed to the suppression of intergranular fracture by the presence of a small amount of solute C.</p>

    <p>The effect of tempering on uniform elongation was investigated for fully lath martensitic steels with 0.2% C by mass. Stress–strain curves were obtained from specimens tempered at 100, 200, 300 and 400°C. Although total elongation rarely depends on the tempering temperature, the uniform elongation decreased while local elongation increased with the tempering temperature. It was found, using precision markers drawn on the specimen surface, that the distribution of the equivalent plastic strain developed during uniform deformation was inhomogeneous in the specimen tempered at 200°C and relatively homogenous in the specimen tempered at 300°C. Finite element analysis suggests that the uniform elongation depends on the volume fraction that continues elastic deformation even after macroscopic yielding. Therefore, the experimental results showing a decrease in the uniform elongation with tempering temperature can be explained by the decrease in the volume fraction that continues elastic deformation immediately after the macroscopic yielding, which is a deformation character specific to low temperature tempered martensitic steels. The range of variation in nanohardness decreased with the tempering temperature, suggesting that the variation in the local yield stress also decreases with the tempering temperature.</p>

    Dislocations emitted from a crack tip in silicon single crystals have been investigated using a high voltage electron microscopy (HVEM). The influence of those crack tip dislocations on the fracture toughness has been discussed based on the 3-D stress analysis of crack-dislocation interaction. Pure screw dislocations were introduced not only ahead of a crack tip but also behind the tip. The dislocations ahead of the crack tip have the sign of Burgers vectors opposite to that of the dislocations behind the tip. These configurations of crack tip dislocations are understood by dislocation loop expansion from sources near the crack tip. The contribution to the fracture toughness by those crack tip dislocations was calculated, and it was found that 70&sim;90% increase in the fracture toughness was caused by a dislocation configuration corresponding to that observed in the early stage of dislocation emission from a crack tip.

    <p>Image-based deformation simulation of microstructures in metals is attracting attention; however, the data conversion processes from the images of microstructures into the geometric models for the deformation simulation are now inconvenient, and there is a possibility that it prevents diffusion of the image-based simulation. In order to solve the problem, we developed an interface to convert the data of crystal orientation maps obtained by Electron Back-Scatter Diffraction (EBSD) patterns into that of geometric models for Crystal Plasticity Finite Element (CPFE) analysis. The interface incorporates several functions for data cleaning and coarse graining of the microstructures: functions to narrow down the limits of Eulerian angles presenting crystal orientations, integrate crystal grains with similar crystal orientations, eliminate small crystal grains, select representative crystal orientation in each crystal grain, and so on. The interface was applied to an orientation map of polycrystal microstructure in pure titanium, and the course-grained geometric models were successfully obtained. Image-based CPFE analysis was conducted using the geometric models with different number of finite elements. The numbers of crystal grains were assumed to be around 50 in any geometric models. A dislocation density dependent constitutive equation was employed and uniaxial tensile loading was applied to the geometric models by the forced displacement. The results showed that spatial distributions of stress, strain, and dislocation density were good agreement among geometric models with different number of elements in both elastic and plastic ranges while values of the strain and dislocation density showed quantitatively dependency of the number of elements on their distributions in the plastic ranges. These features indicate that the qualitatively similar results can be obtained using the developed interface on the condition that coarse graining of the microstructures does not occur even though the number of elements is changed.</p>

    体心立方（BCC）構造を持つ金属は、他の結晶構造にはない特異な変形挙動を示す。本研究では、電子構造と力学特性を繋ぐ新しい手法を開発し、BCC合金系の未知の変形挙動の起源を解明することを目的とする。BCC合金のらせん転位は、電子構造の変化に敏感で、力学特性に強く影響するという予測を立て、転位構造を電子構造に基づく特性として記述する。そして、有限温度の転位の熱活性化過程を捉える方法を開発する。BCC合金の元素設計の鍵を握る第IV族元素について、βチタンを対象とした実験と連携し、BCC合金系の未知の変形挙動の起源を包括的に解明するとともに、優れた力学機能設計に発展させる。

    ハイエントロピー合金には、従来合金には見られない特異で優れた力学特性を示すものが多く見られる。本計画研究では、ナノ・マイクロ力学特性評価法、走査透過電子顕微鏡法、シンクロトロンX線回折法、3次元アトムプローブ法などの先端実験手法を有機的に駆使し、合金の相構成、原子構造、原子移動、変形の主体的担い手としての転位、双晶(転位)、積層欠陥、結晶粒界などを徹底的に解析し、その静的特性のみならず、応力、温度、ひずみ速度、などが異なる種々の環境下での動的応答特性を原子スケールにまで遡って評価し、合金の原子構造、組成、組織と力学特性の相関を予測的に記述する力学特性マップ（構成則）を構築しつつ、金属・合金のみならず金属ガラス、セラミックスなど広範な材料において発現するハイエントロピー効果に基づいた新規で特異な力学特性およびその支配因子を探索・解明し、ハイエントロピー効果の本質を根源的に解明する。特に(1)ハイエントロピー合金の異常に高い低温降伏強度、(2)異常に高い低温引張延性・靭性と低温域における強度と延性の正の相関、(3)高温における異常に高い降伏強度、(4)強度の特異な結晶粒径依存性、(5)原子拡散に関連した高温クリープ強度について重点的に実験研究を行い、2元系や3元系の通常の合金には現れない特異な力学特性の発現メカニズム・ハイエントロピー効果の本質を根源的に解明し、「強くてねばい」夢の革新的構造材料を幅広い材料系で実現するための指針提案に繋げる。
