This study addresses this limitation by deploying a composition control and defect engineering strategy to regulate the martensitic transformation in HTSMAs via a strain glass while preserving elevated transformation temperatures. By introducing 1at.% oxygen as point defects, a Ti<ce:inf loc=\"post\">47</ce:inf>Zr<ce:inf loc=\"post\">47</ce:inf>Nb<ce:inf loc=\"post\">5</ce:inf>O<ce:inf loc=\"post\">1</ce:inf> strain glass alloy with a freezing temperature of about 462 K was fabricated. The microstructure consists of a strain‑glass‑dominated β matrix with minor residual α″ martensite. The low Nb content destabilizes the β phase, enabling the alloy to retain a high transformation temperature of about 745 K. Enabled by the strain glass state and the remarkable theoretical transformation strain derived from the addition of high-content Zr with large atomic radius, this alloy exhibits nearly full recoverability for pre‑strains up to about 5%, and achieves a shape memory recovery strain of ∼5.7% at a pre‑strain of 10%, outperforming most reported HTSMAs. The underlying deformation mechanism is attributed to the stress-induced reversible β → α″ martensitic transformation together with martensitic variant reorientation, which cooperatively accommodate local strains within nanoscale domains.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"10 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884174","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}

Concurrently, manganese-based (Mn-based) cathode materials align exceptionally well with these natures and the electrochemical stability window of aqueous electrolytes, which makes them the most extensively studied cathode materials. However, the underlying degradation mechanisms of Mn-based cathodes in aqueous systems remain to be fully elucidated. Focusing on spinel LiMn<ce:inf loc=\"post\">2</ce:inf>O<ce:inf loc=\"post\">4</ce:inf> (LMO) as a quintessential model material, this review summarizes the development and material genealogies of Mn-based cathodes in ALIBs. Furthermore, both classical and emerging degradation mechanisms are scrutinized in depth, as these insights guide both contemporary and future design strategies. Under specific conditions, LMO can exhibit a kinetically maintained, metastable interfacial buffering regime in which compensating processes temporarily reduce the net degradation rate. However, continued species accumulation and interfacial heterogeneity eventually destabilize this regime, highlighting the need for precise interfacial regulation. Ultimately, this review bridges the degradation mechanisms of aqueous Mn-based cathodes with targeted modulation strategies, enabling high-voltage and long-life Mn-based cathodes for advanced ALIBs.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"2 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884175","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}

Herein, we develop a novel strategy to fabricate multi-heterostructured MMCs with simultaneous strength and ductility enhancement, using a Ti/Mg-6Zn-1.5Mn composite prepared via ultrasonic-assisted semi-solid stirring, homogenization heat treatment, and hot extrusion. The constructed multi-level heterostructures consist of three key features: (i) non-uniform coarse/fine grain (CG/FG) mixed structure, (ii) nanophases with density differences between FGs and CGs, and (iii) Ti particles preferentially distributed adjacent to the nanophases. The composite exhibits exceptional comprehensive mechanical properties, with an ultimate tensile strength of 366 MPa, yield strength of 239 MPa, elongation of 20.6%, and a superior strength-ductility product of 66.29 MJ/m<ce:sup loc=\"post\">3</ce:sup>. The excellent performance originates from multi-heterostructure-driven amplified strain partitioning, which induces hetero-deformation-induced (HDI) strengthening and hardening via geometrically necessary dislocation (GND) accumulation. Meanwhile, activated non-basal slip systems enable efficient intergranular slip transfer for uniform plastic deformation, and CGs effectively delay plastic instability and suppress crack propagation. This work provides new insights into the deformation mechanisms of heterostructured MMCs and offers a feasible pathway for developing advanced lightweight structural materials.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"174 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884172","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}
