At all rolling reductions, the alloy is shown to have a single-phase structure, i.e., only an α-phase solid solution with a bcc structure is detected. The magnetic properties of the alloy decrease as the preliminary rolling reduction increases. The highest magnetic properties are observed at a rolling reduction of 30%; these are Br = 0.91 T, Hc = 46.2 kA/m, and (BH)max = 17.4 kJ/m3.

It was shown that the texture of the β-phase in the VT23 and Mg–8Li–1Al alloys contains components of bcc metals, while the texture of the α-phase is single-component {110}〈100〉 prismatic and differs from the rolling textures of titanium and other metals with the hcp lattice. Variations in the texture of the ε-phase indicate that, during cold rolling, in Fe–17.7Mn steel, only the ε → α' transformation occurs, whereas in Fe–15.9Mn steel, along with the ε → α' transformation, the reverse α' → ε transformation occurs, as a result of which the (110) texture is formed in the ε-phase in the plane of the sheet, as in titanium and magnesium alloys. The lattice deformations as a result of the bcc → hcp transformation were calculated according to the Burgers orientation relationships and were compared with the sheet deformations during rolling. The comparison showed that, for all the studied materials, only one transformation variant occurs; it is characterized by a complete correspondence of the lattice and sheet deformations, in which the {001}〈110〉 orientation of the bcc phase is transformed into the {110}〈100〉 orientation of the hcp phase.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 3","pages":"623 - 631"},"PeriodicalIF":0.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122356","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 classification diagram in the ultimate tensile strength—molybdenum equivalent—aluminum equivalent coordinates is plotted. Relationships are proposed for the rapid evaluation of the strength, plasticity, and impact ductility characteristics depending on the Rockwell hardness level.
