Given their vast compositional space, identifying key factors governing strength and ductility, as well as developing novel strengthening-toughening models to accelerate the property-oriented design, remains an outstanding challenge. Here, we developed an interpretable machine learning (ML) framework for BCC MPEAs to identify the key factors governing yield strength (YS) and fracture elongation (FE). The results demonstrate that FE mainly arises from the synergistic effects of multiple factors (electronegativity difference Δ<em>χ</em>^pauling, valence electron concentration VEC, and density <em>ρ</em>), while average shear modulus mismatch <em>δG</em>^ave is the dominant factor controlling YS. Using these screened features as inputs, we propose optimized YS and FE models that achieve high predictive accuracy (YS: <em>R</em>²=0.96, FE: <em>R</em>²=0.84) and outperform existing models. By transforming these ML insights into strengthening/toughening theories via feature-to-mechanical performance/element property mapping, we designed three novel Ti-Zr-based BCC MPEAs with exceptional properties: YS of 1.07–1.16 GPa, FE of 16.6%–24.5%, and specific yield strength of ∼170 MPa cm³ g^-1, surpassing most reported BCC MPEAs. This work not only provides a data-driven strategy to overcome the strength-ductility trade-off in BCC MPEAs but also establishes interpretable design principles for accelerating the discovery of advanced structural materials.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"35 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, there are pronounced trade-offs between hardness and toughness, and between strength and toughness in HECs. To address these challenges, a dual-phase engineering strategy is proposed in this study to synergistically enhance the mechanical properties of HECs, with (NbMoTaW)C as a representative example. Through the combined effects of TiC solid solution strengthening and in-situ TiO₂ toughening, the (NbMoTaW)C demonstrated superior comprehensive mechanical properties, achieving simultaneously high Vickers hardness (20.23±0.26 GPa), high flexural strength (857±23 MPa), and high fracture toughness (4.97±0.16 MPa m^1/2), thus resolving the trade-offs between these properties. The formation and adjustment mechanisms of the oxide phase were elucidated. The integrated multiscale characterizations and density functional theory (DFT) calculations illustrated that the lattice distortion induced by the TiC solid solution, along with d-orbital hybridization in the electronic structure, resulted in a significant enhancement in both structural stability and mechanical properties of HEC. Furthermore, the TiO₂ particles, strategically formed from oxygen impurities and predominantly located at grain boundaries, significantly enhanced the HEC’s flexural strength. At the same time, the TiO₂ particles remarkably improved the toughness of the HEC through crack deflection, bridging, and branching mechanisms. This work has established a synergistic phase optimization strategy that enables overcoming the traditional trade-offs in mechanical properties of HECs.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"35 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When Ti-55511 alloy was processed at 5 GPa across temperatures (room temperature, 700°C, 900°C), temperature-dependent gradient microstructures were formed and governed by stress heterogeneity. This heterogeneity arises from friction constraints induced by high-pressure stress at the contacting surfaces. The surface region exhibited stress concentration with higher hardness values, while the center region displayed a lower stress state with lower hardness values. A gradient distribution of the shear bands was induced at room temperature, with shear band-assisted phase transformation occurring in the surface region. Comparing the α-phase distributions emerging in the specimens treated in single-phase and dual-phase regions, the stress promoted α precipitation for the former one and suppressed α precipitation for the latter one in the surface region. Notably, a unique α-phase fragmentation mechanism was identified in high-temperature-high-pressure treatment, with the nucleation of the β phase within the α phase, induced by α-to-β phase transformation. When the interior β phase grew up to connect the α/β interfaces on both sides of the α precipitates, the fragmentation process was completed. Besides, dynamic recrystallization occurred in the center of the specimen treated by high-pressure treatment in the single-phase region with limited α precipitation. This leads to a notable enhancement in the mechanical properties, with plasticity increased by over 11% and strength increased by ∼160 MPa compared with the original solid-solution state. These findings demonstrate the uniqueness of the high-pressure thermal treatment process and its potential as a preparation technique for titanium alloys with high-strength and high-ductility.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"31 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comprehensive characterization reveals that entropy-driven structural disorder induces synergistic optoelectronic enhancements, as evidenced by a 33% reduction in exciton binding energy and a prolonged carrier lifetime of 919 ps, both of which contribute to significantly improved charge separation efficiency. The high-entropy architecture further strengthens interfacial processes through enhanced built-in electric fields and improved hydrophilicity. Systematic studies across an entropy increase establish a direct correlation between configurational disorder and photocatalytic performance, highlighting the critical role of entropy in optimizing charge transport and surface reactivity simultaneously.

This achievement was enabled by an integrated innovative approach combining ultrafine micro-nano powders synthesized via laser floating zone melting at 300 μm/s (spacing 0.141 μm), ultrasonic wet sieving for interfacial purification, and low-temperature hot-pressing sintering at 1550°C (150°C below conventional temperatures), full densification within 45 min under 60 MPa pressure is enabled through a plasticity-dominated mechanism synergistically assisted by short-range interfacial diffusion.

Dynamic recrystallization (DRX) has been recognized as an effective mechanism to improve plasticity and strength in coarse-grained materials. However, its activation in NC HEAs at room temperature is typically constrained by insufficient thermal activation and the requirement for extremely high local strains. In this work, a high density of pre-existing nanotwins was introduced into NC CrMnFeCoNi HEA to facilitate DRX through a nanotwin-assisted dynamic recrystallization (ntDRX) mechanism during deformation. The alloy, fabricated by magnetron sputtering, exhibits a single-phase face-centered cubic (FCC) structure with columnar grains of approximately 60 nm. Micropillar compression tests demonstrate a high yield strength of 2.3 GPa and a compressive strain exceeding 40%. During deformation, in addition to dislocation slip and grain boundary (GB) activities, DRX is activated within shear bands, leading to the formation of equiaxed nanograins. These newly formed grains increase interface density, impede dislocation motion, and elevate the flow stress to 2.75 GPa. Additionally, the newly formed GBs of equiaxed grains facilitate GB-mediated deformation at large strains, improving plasticity and suppressing shear localization. Furthermore, tensile experiments reveal two interconnected ntDRX mechanisms. One involves dislocation accumulation at twin boundaries (TBs) leading to subgrain formation through dislocation rearrangement and its evolution into high-angle grain boundaries (HAGBs), while the other involves the direct transformation of coherent TBs into HAGBs through dislocation interactions. This study advances the understanding of room-temperature DRX in NC HEAs and highlights nanotwin engineering as a promising strategy for optimizing mechanical performance.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"25 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145003435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, carbon quantum dots derived from Sophora japonica leaves (SCDs) are innovatively employed as electrolyte additives in alkaline AABs to improve anode corrosion resistance and achieve high-performance output. Corrosion evaluation reveals that 0.2 g L⁻¹ SCDs effectively modulate the interfacial stability of the anode, achieving a corrosion inhibition efficiency of 41.5%.

Precise control of the process parameters plays a fundamental role in achieving the desired characteristics and process optimization has been extensively studied. However, discrepancies persist in the optimization of PBF-EB printed Ti–6Al–4V due to variations in machine configurations, study scopes, and parameter combinations. To address this issue, we herein investigate the individual effects of key parameters-scan speed, line offset, focus offset, and preheating temperature-on surface morphology, porosity, microstructure, and mechanical properties. While focus offset had a limited impact on the microstructure, increasing scan speed or line offset, thus decreasing the energy density, led to a refined microstructure and improved microhardness. However, excessive scan speed, line offset, or focus offset led to insufficient bonding, which compromised the tensile properties. In contrast, reducing scan speed and line offset, thus increasing the energy density, ensured sufficient fusion but yielded a coarse microstructure, which diminishes hardness and tensile strength. The lowest scan speed caused surface distortion and large spherical pores. These results culminated in a process map, which expounded the intricate relationships between the parameters in PBF-EB. These findings not only facilitated the optimization process to achieve fine microstructure and low porosity but may also serve as an anchoring framework for developing new material systems.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"83 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
