The method is based on the experimental determination of the lattice period of an α-solid solution, Vegard’s law, and the balance equations of the chemical and phase compositions. The method was shown to be efficient in assessing the effect of rapid solidification on the ratio of the contents of intermetallic phases in 1441, V-1461, and V-1469 alloys in the Al–Cu–Li system. It was demonstrated that the combined use of quantitative phase analysis and data on the elastic moduli of intermetallic compounds makes it possible to predict the elastic properties of Al–Cu–Li alloys. It was shown that the Young’s modulus is proportional to the amount of intermetallic compounds, which increases more than six times more intensely with increasing lithium content than with increasing copper content. The maximum increase in Young’s modulus as a result of heat treatment at a constant lithium content is 1–2 GPa, and the addition of 1 wt % Li increases Young’s modulus by ≈4 GPa.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 3","pages":"676 - 682"},"PeriodicalIF":0.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A decrease in the static and fatigue strength of as-built samples in the region of low loading amplitudes and an increase in the elongation at fracture have been revealed compared to these characteristics for machined samples. For as-built samples, the appearance of high-amplitude acoustic emission signals indicating the nucleation of surface microcracks at an earlier deformation stage has been detected. It is assumed that knee point on the fatigue curves and amplitude dependences of the characteristic zones size at fracture surfaces are associated with the transition from a plane stress state to a plane strain state of the material with a decrease in the stress amplitude.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 3","pages":"696 - 707"},"PeriodicalIF":0.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
