    Methane (CH4) formation from photocatalytic carbon dioxide (CO2) conversion in water is currently of interest because methane is a fuel, and it can also be transformed into other useful hydrocarbons. However, achieving high selectivity to produce methane remains a challenge because of the large number of contributing electrons (eight) in methanation. High-entropy oxides present a new pathway to tune the catalyst selectivity by arranging various cations in the lattice. This study aims to clarify the selectivity for methane formation in high-entropy photocatalysts containing hybrid d0 + d10 orbital configuration. Several oxides are designed and synthesized which have a base of 3–4 cations with d0 orbital configuration (titanium and zirconium with a valence of 4, and niobium and tantalum with a valence of 5) and incorporate 1–2 elements with d10 orbital configuration (zinc, gallium, indium, bismuth and copper). Results demonstrate that adding elements with a d10 electronic configuration is effective for methane formation, while the selectivity toward methanation is enhanced by increasing the work function of the d10 cations. Selectivity levels over 50 % are achieved using these oxides, suggesting a potential strategy for designing new catalysts for methanation.

    The influence of hydrogen on the precipitation kinetics of L12-Al3Zr ordered precipitates in an industrial Al-Zr alloy was investigated using transmission electron microscopy (TEM) and atom probe tomography (APT). Aging at 375 °C under 10 MPa of hydrogen led to a significant acceleration of Al3Zr precipitate growth, a larger mean precipitate size compared to aging in air, and an enhanced decomposition of the supersaturated solid solution. Fitting experimental data with a coarsening model suggests that hydrogen increases the diffusion coefficient of Zr by a factor of two, likely due to hydrogen-vacancy interactions promoting the mobility of Zr.

    Zinc-ion batteries are promising alternatives to lithium-ion batteries, offering advantages in safety, cost, and environmental impact. However, their performance is often limited by the functioning of the zinc anode. This study employs severe plastic deformation via the high-pressure torsion (HPT) method to enhance the electrochemical performance of zinc anodes. HPT reduced the grain size from > 1000 μm to 20 μm and introduced a (002) basal texture. The battery assembled with HPT-processed zinc demonstrated improved cycling stability, rate performance, and specific discharge capacity (>500 mAh/g at 0.5 A/g after 50 cycles), particularly at high current densities. This performance enhancement was attributed to grain-boundary and texture effects on improved ion transfer (confirmed by electrochemical impedance spectroscopy), fast redox reaction kinetics (confirmed by cyclic voltammetry), and reduced corrosion (confirmed by microscopy and potentiodynamic polarization test). This study highlights the potential of severely deformed materials with textured fine grains for advanced rechargeable battery technologies.

    The persistent existence of plastic waste causes serious problems for the environment, directly and indirectly affecting the health of organisms and humans. Photoreforming is a nature-friendly method that only uses solar energy to convert plastic waste into green hydrogen (H2) and valuable organic products. This study shows that a high-entropy oxynitride (HEON) photocatalyst, synthesized by the addition of nitrogen to a Ti-Zr-Hf-Nb-Ta-containing high-entropy oxide (HEO), exhibits a higher potential for the production of H2, formic acid and acetic acid from polyethylene terephthalate (PET) photoreforming compared to the relevant HEO. Examination of X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) by synchrotron light shows that, in addition to hybridization of 2p orbitals from oxygen and nitrogen, nitrogen atoms distort the structure and completely change the neighborhood of niobium and titanium (a main contributor to the conduction band), expands the atomic bonds of zirconium and tantalum, contracts the atomic bonds of hafnium and decreases the binding energy of titanium, niobium and tantalum. These electronic structure changes lead to a narrower bandgap and diminished electron-hole recombination, enhancing the photoreforming performance. This study introduces HEONs with distorted atomic-bond structures as efficient low-bandgap and stable catalysts for transforming plastics into high-value organic chemicals and H2 by photocatalysis.

    <p>Titanium and Ti-based materials are advanced materials that have found applications across various fields of science and engineering. Over the past three decades, significant efforts have been made to employ severe plastic deformation (SPD) via the high-pressure torsion (HPT) method on Ti-based materials. These efforts aim to achieve ultrafine grains with a high density of lattice defects, control phase transformations, and synthesize new compounds. Pure titanium, and Ti-containing alloys, intermetallics, ceramics and composites have been processed by HPT to enhance mechanical and functional properties. These properties include high hardness, high strength combined with plasticity, biocompatibility, superconductivity, dielectric performance, photocatalysis, electrocatalysis and photovoltaic capabilities. Additionally, the synthesis of new high-entropy alloys and ceramics via HPT has emerged as a promising direction, contributing to various disciplines such as photocatalysis, biomedical devices and hydrogen storage. This article provides a brief overview of the SPD concept and the HPT method, followed by a summary of recent advances in the HPT processing of Ti-based materials.</p>

    One of the most significant challenges in using hydrogen as a substitute for fossil fuels is designing alloys that can store hydrogen in solid form. These alloys must facilitate reversible reactions over long cycles, with fast kinetics at room temperature. Given the potential of high entropy alloys (HEAs) for safe, and high-density hydrogen storage, this study combines semi-empirical descriptors (atomic size mismatch, atomic radius ratio of hydride-forming to non-hydride-forming elements, and valence electron concentration), thermodynamic calculations via CALPHAD, and machine learning (ML) to design two novel alloys Ti20Zr20Mn20Fe20Co20 and Ti15Zr22Mn27Fe26Co10. While empirical descriptors and CALPHAD were used to select alloys with a high tendency to form the C14 Laves phase, ML was employed to predict the enthalpy of hydride formation, a critical thermodynamic parameter for hydrogen storage. The synthesis of these two HEAs and subsequent experimental investigations, using pressure-composition-temperature (PCT) isotherm and absorption kinetic measurements, revealed that the Ti20Zr20Mn20Fe20Co20 and Ti15Zr22Mn27Fe26Co10 alloys absorb 1.5 wt% of hydrogen with fast kinetics and reversibility at room temperature for at least ten cycles. The predicted enthalpy by ML closely matches the measured enthalpy, demonstrating the potential of artificial intelligence approaches in estimating fundamental thermodynamic parameters to design new hydrogen storage materials.

Initially gaining prominence in the early 2000s for microstructure control and mechanical property enhancement, SPD is now increasingly applied to improve functional properties, particularly in biomedical, energy, and hydrogen-related applications. The scope of SPD has expanded from metallic materials to encompass a wide range of non-metallic materials, including ceramics and polymers. Additionally, SPD methods have provided insights into natural phenomena involving high strain and pressure, such as phase transformations and certain geological and astronomical processes. This article reviews recent research trends, as highlighted in the 2023 special issue of Materials Transactions entitled “Superfunctional Nanomaterials by Severe Plastic Deformation”, focusing on recent advancements and interdisciplinary applications of SPD.</p>

    This study presents the design and evaluation of a medium entropy alloy (MEA), Ti21Zr21Fe41Ni17, for hydrogen storage at room temperature (30 °C), employing an integrated design approach that combines CALPHAD calculations with semiempirical rules. The alloy was developed based on four specific design criteria: (1) valence electron concentration (VEC) between 6.2 and 6.5, (2) atomic size mismatch (δ) of at least 9.7%, (3) an atomic radius ratio of hydride-forming to non-hydride-forming elements (rA/rB) ranging from 1.149 to 1.219, and (4) stability of the C14 Laves phase as the primary phase, as confirmed by CALPHAD. The resulting alloy crystallized predominantly in the C14 Laves phase (92.8 wt %), with a minor body-centered cubic (BCC) phase. Transmission electron microscopy (TEM) results revealed coherent nanograin boundaries, particularly at the C14/BCC interphase, facilitating rapid hydrogenation kinetics. After a one-step simple thermal activation, the alloy reversibly absorbed 1.4 wt % of hydrogen with relatively low hysteresis and fast kinetics, attributed to a preferential hydride nucleation at grain boundaries. In terms of thermodynamic properties, the chemical composition, designed according to the aforementioned criteria, should be considered, with the high iron content (41%) playing a critical role. The high atomic percentage of iron, a non-hydride-forming element, stabilizes the C14 phase due to the significant negative contribution of the interaction parameter (Ωij) of the Fe-Zr pair (Ωij = −118.4 kJ/mol), which results in a negative enthalpy of mixing in the C14 structure. This work underscores the utility of combining CALPHAD and semiempirical design methods while outlining critical challenges and future directions for optimizing MEAs for hydrogen storage.

    This study evaluated the effect of severe plastic deformation via high-pressure torsion (HPT) on the microstructure and mechanical properties of Fe-23Mn-0.5 C (wt%) twinning-induced plasticity (TWIP) steel. The annealed steel was subjected to HPT at a pressure of 6 GPa and 30 turns of rotation. Following deformation, some discs were annealed at 673 K for 1 hour. The microstructures were examined using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Severe plastic deformation resulted in a substantial reduction in austenite grain size, along with the formation of ε-martensite, indicating the activation of the transformation-induced plasticity (TRIP) effect. Consequently, the hardness increased by nearly 300 %, the coefficient of friction (CoF) decreased, and the wear volume loss was reduced by over four-fold compared to the initial steel. The annealing of the HPT-processed material led to a slight softening due to recrystallization and reverse martensitic phase transformation. However, this thermal treatment resulted in the formation of nanotwins coupled with fine recrystallized grains which kept wear resistance at the same level.

    To enhance the activity of photocatalysts for hydrogen production and CO2 conversion, noble metal cocatalysts as electron traps and/or acceptors such as platinum or gold are usually utilized. This study hypothesizes that mixing elements with heterogeneous electronic configurations and diverse electronegativities can provide both acceptor and donor sites of electrons to avoid using cocatalysts. This hypothesis was examined in high-entropy oxides (HEOs), which show high flexibility for atomic-scale compositional changes by keeping their single- or dual-phase structure. A new high-entropy oxide was designed and synthesized by mixing elements with an empty d orbital (titanium, zirconium, niobium and tantalum) and a fully occupied d orbital (gallium). The oxide, synthesized by high-pressure torsion followed by calcination, had two phases (88 wt% orthorhombic (Pbcn) and 12 wt% monoclinic (I2/m)) with an overall composition of TiZrNbTaGaO10.5. It exhibited UV and visible light absorbance with a low bandgap of 2.5 eV, low radiative electron-hole recombination and oxygen vacancy generation due to mixed valences of cations. It successfully acted as a photocatalyst for CO and CH4 production from CO2 conversion and hydrogen production from water splitting without cocatalyst addition. These findings confirm that introducing heterogeneous electronic configurations and electronegativities can be considered as a design criterion to avoid the need to use cocatalysts.

    Cadmium sulfide (CdS) is a well-known low-bandgap photocatalyst, but its efficiency is often hindered by rapid photo-generated carrier recombination and a limited number of active catalytic sites. To overcome these challenges, this study introduces an efficient CdS photocatalyst through a novel strategy combining metastable-to-stable phase transformation and sulfur vacancy generation. This strategy integrates hydrothermal treatment and a high-pressure process to create sulfur vacancies, which serve as active catalytic sites, within a thermodynamically stable wurtzite (hexagonal) phase known for its superior photocatalytic properties. The resulting CdS photocatalyst demonstrates exceptional performance in photoreforming for hydrogen production and the conversion of polyethylene terephthalate (PET) plastic into valuable materials. Compared to commercial CdS catalysts, this new material shows a 23-fold increase in both hydrogen production and plastic degradation without the need for co-catalysts. Quenching experiments reveal that holes and hydroxyl radicals play crucial roles in the photoreforming process of this vacancy-rich CdS. First-principles calculations via density functional theory (DFT) indicate that the hexagonal phase possesses a lower bandgap and it exhibits further bandgap narrowing with the introduction of sulfur vacancies. These findings not only present an innovative approach to CdS processing but also highlight the critical role of sulfur vacancies as effective defects for the catalytic photoreforming of microplastics.

    High-entropy alloys (HEAs) are potential candidates for applications as refractory materials. While dual-phase refractory HEAs containing an ordered phase exhibit high hardness, there is high interest in developing intermetallic-free and single-phase refractory HEAs with high hardness. In this study, a new equiatomic HEA ZrHfNbTaW with an ultrahigh hardness of 860 Hv is developed. The alloy is first synthesized with a dual-phase structure via arc melting and further homogenized to a single body-centered cubic (BCC) structure by phase transformation via high-pressure torsion (HPT), using the concept of ultra-severe plastic deformation process. The ultrahigh hardness of the alloy, which is higher than those reported for refractory alloys and single-phase HEAs, is attributed to (i) solution hardening by severe lattice distortion, (ii) Hall-Petch grain boundary hardening by the formation of nanograins with 12 nm average size, and (iii) dislocation hardening confirmed by high-resolution transmission electron microscopy.

    To make hydrogen a more viable energy carrier, various solutions for hydrogen storage have been developed, with significant recent progress in developing new high-entropy alloys (HEAs) that exhibit attractive hydrogen storage properties. In this paper, we investigated the crystal structure and hydrogen storage properties of a new medium-entropy alloy (MEA) ZrNbFeCo, designed using a combination of semi-empirical parameters and thermodynamic calculations via the CALPHAD method. The alloy was synthesized by arc melting under an argon atmosphere and subsequently characterized using comprehensive techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). These analyses revealed the presence of a major C14 Laves phase, with a compositional gradient and grain sizes ranging from microscale to nanoscale. The hydrogen storage properties were evaluated using pressure-composition isotherms (PCI) and kinetics curves. After a simple activation procedure, the alloy formed a C14 hydride and exhibited excellent properties to act as a vessel for hydrogen storage at room temperature. Under these conditions, the alloy was able to absorb up to 1.2 wt% of hydrogen (hydrogen-to-metal ratio of H/M ∼ 0.9), with fast absorption kinetics, reaching around 87 % of its maximum capacity after just 60s. The alloy also exhibited full reversibility and great stability through multiple absorption-desorption cycles, absorbing an average content of 1.1 wt% of hydrogen (H/M ∼ 0.82) after 8 cycles. The present results demonstrate that it is possible to practically employ semi-empirical and thermodynamics calculations, originally developed for HEAs, to develop new MEAs that exhibit appropriate microstructure and excellent hydrogen storage properties at room temperature.

    Zinc oxide（ZnO）with a rocksalt crystal structure is attractive because of the bandgap which lies in the range of visible light absorption （1.2-2.6 eV）. However, the rocksalt structure is not stable at ambient pressure and temperature according to an equilibrium phase diagram. Nevertheless, this study demonstrates, for the first time, that it is possible to realize a 100% fraction of the rocksalt structure at ambient pressure and temperature. ZnO powder is initially processed by severe plastic deformation under high pressure through a technique of high-pressure torsion （HPT）. The HPT-processed ZnO is then examined using a high-pressure application system available at BL04B1 of SPring-8 and in situ X-ray diffraction（XRD）analysis is conducted under high pressures at elevated temperatures. It is shown that the initial presence of the rocksalt structure produced by the HPT process is effective to attain a 100% fraction of the rocksalt structure.

    A high-pressure torsion（HPT）processed Fe-21Cr-5Ni-2Mo（mass%）two-phase stainless steel was used to study the morphology and crystallographic features of austenite（γ）precipitated from ferrite（α）during aging in the（α + γ）two-phase region. The starting material was a gas-atomized powder with a completely ferritic structure. The HPT process was carried out to produce a fully dense compact under 6 GPa for 5 revolutions. The compact was given an equivalent strain of about 130. After the HPT process, the matrix ferrite formed a pancake–like nanograined structure with a strong texture, i.e. ND（Normal Direction）// {110} α. By annealing at 1173 K for 3.6 ks, an ultrafine（α + γ）microduplex structure with high-angle grain boundaries was formed. In addition, the strong texture formation of {110} α / {111} γ / ND plane was formed in the α and the γ grain duplex structure. The α and γ phases had average grain sizes of 2.1 μm and 1.6 μm, respectively. The area fraction of the γ phase was 37.2%, which exceeded that of a cold-pressed compact, 6.7%. Both ultrafine grain refinement and γ precipitation were accelerated by the HPT process. In other words, the application of the HPT process to the two-phase alloys enables the formation of the ultrafine microduplex structure. The Kurdjumov-Sachs（K-S）orientation relationship between α and γ phases is usually observed in the alloy, however, the K-S orientation relationship was not dominant except for the close packing plane parallel orientation relationship, {110} α / {111} γ, in the HPT-processed material.

    Developing nanostructured bulk ceramics is a major challenge when conventional high-temperature sintering is employed for consolidation. In the current investigation, yttria-stabilized zirconia (YSZ) with a composition of ZrO2 - 3 mol% Y2O3 is first treated using high-pressure torsion (HPT) and further consolidated using spark plasma sintering (SPS) to produce a nanostructured bulk sample. The material demonstrates phase transformations from tetragonal to dislocation-decorated monoclinic by HPT and reversely transforms to the tetragonal phase after the SPS process while maintaining a mean grain size of 80 nm and large numbers of dislocations. The consolidated ceramic exhibits a density of 6.07 g/cm3 (99 % relative density) with a high hardness of 1500 Hv, which is reasonably consistent with the prediction of the Hall-Petch relationship. Examination of the indented areas during the hardness test confirms the absence of cracks, indicating good fracture toughness (KIC) because of the presence of dislocations, while the sample processed only by SPS and without HPT processing forms numerous cracks by indentation and exhibits low KIC.

    Bismuth (III) oxide (Bi2O3) has been highly studied as a photocatalyst for green hydrogen production due to its low band gap, yet its efficiency requires enhancement. This study synthesizes a defective and strained black Bi2O3 by severe straining under high pressure, via a high-pressure torsion method, to improve its photocatalytic hydrogen production. The material rich in oxygen vacancies exhibits a ten-fold improvement in water splitting with excellent cycling stability. Such improvement is due to improved light absorption, narrowing band gap and reduced irradiative electron-hole recombination. Moreover, the valence band bottom energy positively increases by straining leading to a high overpotential for hydrogen production. This research highlights the potential of vacancies and lattice strain in developing dopant-free active catalysts for water splitting.

    Photoreforming is a sustainable photocatalytic process that degrades plastic waste while simultaneously producing hydrogen (H2) from water. However, this process has received limited attention due to the scarcity of effective catalysts capable of both plastic degradation and H2 production, such as titanium dioxide (TiO2). In this study, an active catalyst is developed by stabilizing the high-pressure orthorhombic phase of TiO2, known as columbite, using a high-pressure torsion (HPT) method. This material effectively degrades polyethylene terephthalate (PET) plastic under light, converting it into valuable organic compounds such as formic acid, terephthalate, glycolic acid, and acetic acid. Additionally, it produces a significant amount of H2. The findings show that the high-pressure orthorhombic phase, especially in the presence of oxygen vacancies, enhances catalytic H2 production and microplastic degradation by increasing light absorption, reducing electron-hole recombination, and generating hydroxyl radicals. These results highlight the substantial potential of modified high-pressure TiO2 photocatalysts in simultaneously addressing the plastic waste crisis and the demand for H2 fuel.

    This study explores the effects of high-pressure torsion (HPT) processing on the microstructural and mechanical properties of Cu-30Zn alloy. Thin disc specimens of annealed Cu-30Zn were subjected to HPT at room temperature under a pressure of 6 GPa with 10 rotational turns. Microstructural analysis using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed a significant refinement to an ultrafine-grained structure with grain sizes mainly below 100 nm, increased dislocation density, and the formation of mechanical nanotwins. This microstructural transformation resulted in a remarkable increase in Vickers microhardness by approximately 250 %, from 79 ± 4 HV in the annealed state to 275 ± 7 HV after HPT processing. Additionally, scratch resistance tests demonstrated improved performance in the HPT-processed alloy, with reduced wear volume loss, lower coefficient of friction, and more uniform scratch track morphology compared to the annealed material. These results indicate that HPT processing enhances the hardness and wear resistance of Cu-30Zn alloys, suggesting its potential for applications requiring high durability and strength, given the limited hardening mechanism and wear resistance of conventional single-phase brass.

    Aqueous zinc-ion batteries, with their high capacity and stable zinc anode, are a promising choice for large-scale energy storage systems. To fabricate promising cathode materials for aqueous zinc-ion batteries, the VO2(M)-C composite was designed and synthesized in this work by a simple hydrothermal reaction and high-temperature calcination. The VO2(M)-C composite undergoes an in situ electrochemical conversion during the initial cycle of activation when it is charged to 1.4–1.55 V, generating Zn2(V3O8)2 with large layer spacing and a stable structure. The activated cathode material exhibited high specific capacity (520.64 mA h g−1 at 0.5 A g−1) and excellent cycling stability (215.17 mA h g−1 after 1000 cycles at 20 A g−1). These excellent performances are mainly attributed to the high pseudo-capacitance contribution ratio as well as the good electronic conductivity and fast ionic diffusion. This study brings new prospects of designing high-performance cathode materials for aqueous zinc-ion battery.

    This study investigates the dislocation density in ceramics processed by severe plastic deformation at room and elevated temperatures via high-pressure torsion (HPT) for various numbers of turns and shear strains. Ceramics, characterized by ionic or covalent bonding, typically exhibit brittleness due to limited dislocation activity. However, HPT enables significant microstructural transformations in ceramics including dislocation nucleation and accumulation. Despite recent advances in the visualization of such dislocations by transmission electron microscopy (TEM), there is a lack of comprehensive reports on the quantification of dislocation density in severely deformed ceramics. This paper addresses this gap by employing X-ray diffraction (XRD) analysis to quantify dislocation density and crystallite size in a few oxide ceramics. Results demonstrate that HPT induces exceptionally high dislocation densities comparable to theoretical upper limits of dislocation density in ceramics, on the order of 1015 to 1016 m−2, with crystallite sizes reduced to the nanometer scale. These findings significantly enhance the understanding of dislocation behavior in ceramics and suggest a potential approach for tuning the mechanical and functional properties of these materials by dislocations.

    Simultaneous catalytic hydrogen (H2) production and plastic waste degradation under light, known as photoreforming, is a novel approach to green fuel production and efficient waste management. Here, we use a high-entropy oxide (HEO), a new family of catalysts with five or more principal cations in their structure, for plastic degradation and simultaneous H2 production. The HEO shows higher activity than that of P25 TiO2, a benchmark photocatalyst, for the degradation of polyethylene terephthalate (PET) plastics in water. Several valuable products are produced by photoreforming of PET bottles and microplastics including H2, terephthalate, ethylene glycol and formic acid. The high activity is attributed to the diverse existence of several cations in the HEO lattice, lattice defects, and appropriate charge carrier lifetime. These findings suggest that HEOs possess high potential as new catalysts for concurrent plastic waste conversion and clean H2 production.

    Photocatalysis offers a sustainable solution for essential reactions such as CO2 conversion and water splitting, but constraints in catalyst properties like bandgap and active site availability often limit its efficiency. High-entropy oxides (HEOs), which incorporate five or more different cations, present significant potential for this application due to their elemental diversity. This study explores active HEO development for photocatalytic applications by integrating cations with d0 and d10 electronic configurations. A single-phase HEO with a monoclinic structure was successfully synthesized, comprising elements with d0 (titanium, zirconium, niobium and tantalum) and d10 (zinc) electronic configurations. Comprehensive analyses of its microstructure, chemical composition, optical properties and photocatalytic activity were conducted. The resulting TiZrNbTaZnO10 exhibited superior UV and visible light absorption, a low bandgap of 2.5 eV, minimal radiative electron-hole recombination and high stability under photocatalytic conditions. Remarkably, TiZrNbTaZnO10 outperformed the TiZrHfNbTaO11 photocatalyst which contains solely d0 electronic configuration. This enhanced performance is attributed to the mixed electronic configurations fostering heterogeneous chemical environments, which facilitate efficient charge carrier separation and transfer.

    For the purpose of enhancing the structural insights within the three-dimensional composition fields revealed by atom probe tomography, correlative microscopy approaches, combining (scanning) transmission electron microscopy with atom probe tomography, have emerged and demonstrated their relevance. To push the boundaries further and facilitate a more comprehensive analysis of nanoscale matter by coupling numerous two- or three-dimensional datasets, there is an increasing interest in combining transmission electron microscopy and atom probe tomography into a unified instrument. This study presents the tangible outcome of an instrumental endeavour aimed at integrating atom probe tomography into a commercial transmission electron microscope. The resulting instrument demonstrates the feasibility of combining in situ 3D reconstructions of composition fields with the detailed structural analysis afforded by transmission electron microscopy. This study shows a promising approach for converging these two important nanoscale microscopy techniques.

    Microstructure design of new high-performance alloys requires the combination of multiple hardening mechanisms. This study explores combining nanograins with spinodal decomposition strengthening in an Fe-51.4Cr (at.%) alloy. High-pressure torsion (HPT) produced a nanostructure with a 51 nm grain size. Atom probe tomography analysis of deformed and annealed samples revealed spinodal decomposition after one hour of annealing. HPT accelerated decomposition kinetics is due to the high vacancy concentration. Microhardness remained stable due to spinodal hardening, despite a decrease in the Hall-Petch strengthening contribution. However, fracture toughness decreased.

    Ultrafine-grained and heterostructured materials are currently of high interest due to their superior mechanical and functional properties. Severe plastic deformation (SPD) is one of the most effective methods to produce such materials with unique microstructure-property relationships. In this review paper, after summarizing the recent progress in developing various SPD methods for processing bulk, surface and powder of materials, the main structural and microstructural features of SPD-processed materials are explained including lattice defects, grain boundaries and phase transformations. The properties and potential applications of SPD-processed materials are then reviewed in detail including tensile properties, creep, superplasticity, hydrogen embrittlement resistance, electrical conductivity, magnetic properties, optical properties, solar energy harvesting, photocatalysis, electrocatalysis, hydrolysis, hydrogen storage, hydrogen production, CO2 conversion, corrosion resistance and biocompatibility. It is shown that achieving such properties is not limited to pure metals and conventional metallic alloys, and a wide range of materials are currently processed by SPD, including high-entropy alloys, glasses, semiconductors, ceramics and polymers. It is particularly emphasized that SPD has moved from a simple metal processing tool to a powerful means for the discovery and synthesis of new superfunctional metallic and nonmetallic materials. The article ends by declaring that the borders of SPD have been extended from materials science and it has become an interdisciplinary tool to address scientific questions such as the mechanisms of geological and astronomical phenomena and the origin of life.

    Plastic waste entering the environment through landfilling or improper disposal poses substantial risks to ecosystems and human health. Photoreforming is emerging as a clean photocatalytic technology that degrades plastic waste to organic compounds while simultaneously producing hydrogen fuel. This study introduces high-pressure torsion (HPT), a severe plastic deformation (SPD) method, as an innovative technique to enhance the photoreforming of polypropylene (PP) plastic mixed with a brookite TiO2 photocatalyst. Hydrogen production systematically increases with the number of HPT turns, accompanied by the formation of valuable small organic molecules. The enhancement in photocatalytic activity is attributed to strain-induced defect formation in both catalysts and plastics, as well as the creation of catalyst/plastic interphases that enhance charge carrier transport between inorganic and organic phases. These findings reveal a new functional application for SPD in energy conversion and sustainability.

    High-entropy oxides (HEOs), containing at least five principal cations, have recently emerged as promising photocatalysts for hydrogen production via water splitting. Despite their high potential, the impact of the cation mixtures on photocatalytic activity remains poorly understood. This study investigates the high-entropy photocatalyst TiZrHfNbTaO11 using first-principles calculations combined with experimental methods to elucidate the effects of various elements on electronic structure and water splitting performance. The results indicate that the HEO exhibits a bandgap comparable to TiO2 polymorphs rutile, brookite and anatase. Cations with lower electronegativity, such as hafnium and zirconium, provide the strongest water adsorption energy, serving as active sites for water adsorption. Additionally, the co-presence of highly electronegative cations like niobium and tantalum adjacent to hafnium and zirconium enhances charge transfer to water molecules, improving splitting efficiency. These findings suggest novel strategies for designing high-entropy photocatalysts by synergistic incorporating cations with different electronegativities.

    This study examines the corrosion resistance of ultrafine-grained Al0.1CoCrFeNi high-entropy alloy processed by high-pressure torsion (HPT), focusing on stored energy, diffusion, and the high-entropy effect. Microstructural analysis revealed a single-phase FCC structure with numerous defects and reduced crystallite size following the HPT process. Samples with higher HPT turns formed high-angle grain boundaries, equiaxed nanograins, and numerous nanotwins, contributing to a notable increase in Vickers microhardness from 159 Hv for the initial sample to 550 Hv after 5 turns of HPT. Corrosion behavior is found to be influenced by stored energy and chromium diffusion. Low HPT turns increased the corrosion rate due to sluggish diffusion of chromium and high stored energy in the form of dislocations. Conversely, corrosion resistance improved with increased HPT turns due to fast diffusion through non-equilibrium grain boundaries and the formation of nanotwins with lower stored energy. These findings suggest that a relatively low entropy plays a critical role in the chromium segregation from the solid solution for forming a passive film and enhancing corrosion resistance.

    Safe and high-density storage of hydrogen, for a clean-fuel economy, can be realized by hydride-forming materials, but these materials should be able to store hydrogen at room temperature. Some high-entropy alloys (HEAs) have recently been shown to reversibly store hydrogen at room temperature, but the design of HEAs with appropriate thermodynamics is still challenging. To explore HEAs with appropriate hydride formation enthalpy, this study employs machine learning (ML), in particular, Gaussian process regression (GPR) using four different kernels by training with 420 datum points collected from literature and curated here. The developed ML models are used to predict the formation enthalpy of hydrides for the TixZr2-xCrMnFeNi (x = 0.5, 1.0 and 1.5) system, which is not in the training set. The predicted values by ML are consistent with data from experiments and density functional theory (DFT). The present study thus introduces ML as a rapid and reliable approach for the design of HEAs with hydride formation enthalpies of −25 to −39 kJ/mol for hydrogen storage at room temperature.
