Alternating bending deformation by one- and two- pass rolling monotonically increases the yield strength of the annealed (at 420°C) alloy from 99 to 133 MPa (by 34.8% relative to its annealed state) without changing the strip geometry and its ductility. Annealing at 300°C increases the yield strength to 300 MPa but reduces ductility. Subsequent alternating bending does not change the mechanical properties of the alloy.</p>","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 5","pages":"1145 - 1150"},"PeriodicalIF":0.4000,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":"0","resultStr":null,"platform":"Semanticscholar","paperid":null,"PeriodicalName":"Russian Metallurgy (Metally)","FirstCategoryId":"5","ListUrlMain":"https://link.springer.com/article/10.1134/S0036029524702148","RegionNum":0,"RegionCategory":null,"ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":null,"EPubDate":"","PubModel":"","JCR":"Q4","JCRName":"METALLURGY & METALLURGICAL ENGINEERING","Score":null,"Total":0}
