Here, we report a hierarchical microstructure tailoring strategy to achieve an excellent strength-ductility combination in Ti-4Al-5Mo-5V-5Cr-1Nb (Ti-45551) alloy. It was revealed that high density deformation twinning can be successfully introduced in primary α particles of Ti-45551 alloy through warm dynamic plastic deformation (DPD). After warm DPD process, the hierarchical microstructure was constructed in Ti-45551 alloy, including equiaxed primary α particles with high density deformation twins, β-phase matrix and finely dispersed nanoscale secondary α lamellas. Uniaxial tensile experiments have revealed that Ti-45551 alloy exhibited enhanced strength-ductility synergy with hierarchical microstructure at room temperature. This excellent combination of strength and ductility is derived from high twin density in in primary α particles and unique hierarchical microstructure. Also, this study demonstrates a feasible and low-cost route to design high performance Ti alloy.</p></div>","PeriodicalId":18245,"journal":{"name":"Materials Letters: X","volume":"16 ","pages":"Article 100168"},"PeriodicalIF":1.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590150822000485/pdfft?md5=46626d99f127f7b954a98ab37442a7d1&pid=1-s2.0-S2590150822000485-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42662552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
