The LCR (Limiting Cold-Rolling ratio) at room temperature tended to increase with increasing area fraction of the Mg0.1In0.9 phase, and the LCR achieved 80% for the single Mg0.1In0.9 phase in both alloys. The hardness value of the Mg0.1In0.9 phase in the Mg–In binary alloys increased after rolling originated from grain-refinement by recrystallization and precipitation hardening due to processing heat generated by rolling at room temperature. On the other hand, the Mg0.1In0.9 phase formed in the Mg–Al–In ternary alloys was stable at room temperature and work hardened after rolling. Since the Mg0.1In0.9 phase dissolves about 5 mol% of Al, substituting Al for In in the Mg–In alloy was effective in reducing density. The density of the Mg80Al7In13 (mol%) alloy is 2.60 Mg/m3, which is lower than that of Al, and the LCR showed 49%. In Mg–In alloys, the substitution of Al is effective in developing alloys that are easy to process at room temperature and have low density, because the Mg0.1In0.9 phase has a solid solution of Al and contributes to phase stabilization at room temperature.","PeriodicalId":18402,"journal":{"name":"Materials Transactions","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136265495","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}

In the present study, first-principles calculations were carried out to evaluate the two- and three-body interactions between Mg, Si atoms and vacancies in the Al matrix and estimate the effect of local bonding on the formation of nanoclusters. Monte Carlo simulations were subsequently performed to investigate the stable structure of the nanocluster formed in Al–0.95 mass pct Mg–0.81 mass pct Si alloy. We found that the Mg–Si and Si–Vac pairs are stable in the Al matrix. The result shows that the solute atoms easily aggregate with different types of solute atoms and that the Si atom has a strong attractive interaction with a vacancy. Furthermore, Mg–Si–vacancy triplets are more stable than Mg–Si and Si–vacancy pairs in the Al matrix. The nanoclusters in the Al matrix were thermally stabilized by the stable configurations between solute atoms and vacancy. Thus, the electronic structure calculations suggested that the local bondings within a nanocluster play a significant role in not only the thermal stability but also the formation and growth behavior of nanoclusters during aging at low temperatures.","PeriodicalId":18402,"journal":{"name":"Materials Transactions","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135872426","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}
