The results are used to construct plots and to find the regularities of changes in the hardness as a function of the mechanical properties and the degree of cold deformation of the strips made of nonferrous alloys of known chemical compositions. Regression equations are derived to calculate the main hardness characteristics and mechanical properties on rolling nonferrous metal strips. The adequacy of the equations confirmed by high correlation coefficients (<i>R</i><sup>2</sup> &gt; 0.9) allows us to recommend them for calculating the force characteristics of rolling and designing in computer-aided design (CAD) for rolling of strips and ribbons made of nonferrous metals (AD33 aluminum alloy, M0 copper alloy) on industrial rolling mills.</p>","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 7","pages":"1776 - 1782"},"PeriodicalIF":0.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655334","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}

The introduction of the sulfur-containing additives into a citrate–succinate solution stabilizes the deposition of a Ni–P–W alloy within at least 60 min. Thiourea and thiamine chloride do not allow the formation of deposits simultaneously with a high tungsten content and at a satisfactory deposition rate. Stabilizers 2-MBT and SPS make it possible to conduct deposition at higher rates with a high tungsten content. Depending on the number of amino groups in the molecule, different effects of the stabilizer concentration on the fraction of codeposited sulfur are observed. In the cases of SPS and 2-MBT, the sulfur fraction increases linearly with an increase in the stabilizer content. The sulfur fraction in the coating remains unchanged with increasing concentration when thiourea is used, and the sulfur content decreases with increasing concentration for thiamine chloride.</p>","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 7","pages":"1638 - 1644"},"PeriodicalIF":0.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655317","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}
