However, increased strength is often accompanied by reduced fracture toughness, severely limiting their safe application under extreme loading. This paper systematically reviews recent progress in the fracture toughness research of high-strength steels. It begins by explaining the theoretical foundations of fracture mechanics, followed by an analysis of standard test methods, small-specimen testing techniques, and the correlation between fracture toughness and other mechanical properties. And introduced DIC and in situ SEM testing techniques. Furthermore, the mechanisms of toughness improvement through composition design, microstructure control, and processing optimization are discussed in depth. The coupling effect of environmental factors and loading conditions is also analyzed, along with the microscopic fracture mechanisms under the combined influence of composition, processing, and environment. Research indicates that optimizing alloy composition, developing innovative processes, and advancing small-specimen evaluation methods can effectively balance strength and toughness. Future research should focus on elucidating multi-element interaction mechanisms, extreme environmental adaptability, and cross-scale mechanical modeling to provide theoretical support for designing the next generation of high-strength steels.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 5","pages":"3904 - 3930"},"PeriodicalIF":2.3,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147755923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These steels, typically martensitic, offer exceptional strength but are often limited in cold-forming applications due to reduced ductility at room temperature. Accordingly, this study investigated two representative cold-forming UHSS1500 grades: DP1470, a dual-phase steel offering enhanced global ductility for improved formability, and MS1500, a fully martensitic steel providing superior local ductility for increased fracture resistance. Through comprehensive mechanical evaluations, including quasi-static, temperature-, strain-rate- and stress-state-dependent experiments, this work highlights the key microstructural mechanism: incorporating ferrite in DP1470 could effectively improve its global formability but compromise its bake-hardenability and local ductility; comparatively, the homogeneous microstructure in MS1500 resulted in higher bake-hardening response and fracture resistance under localized deformation and crash-relevant conditions. These findings underscored a critical design trade-off between global and local performance, offering guidance for application-specific material selection and future UHSS microstructural development strategies.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 5","pages":"3940 - 3952"},"PeriodicalIF":2.3,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147755917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
