Such large levels of deformation are usually achievable in high pressure twisting of small flat disks, but are difficult to achieve in large bulk bars. The method of radial shear rolling makes it possible to achieve comparable ultrahigh degrees of deformation (~45 mm/mm) in combination with the vortex flow of the metal. Sequential rolling of the E110 zirconium alloy was carried out under extreme conditions on 2 radial shear rolling mills with a total diameter reduction ε = 185 % and a maximum accumulated strain = 46 mm/mm. To assess the level of deformation and its distribution over the section, FEM modeling was carried out in Deform‑3D. The resulting structure was studied by electron microscopy (TEM/SEM). A detailed cross‑sectional study of the EBSD structure was performed with a resolution of 1 mm. A gradient structure with a predominance of an equiaxed ultrafine‑grained structure was found, which was not very pronounced compared to the use of smaller deformations.","PeriodicalId":278844,"journal":{"name":"Litiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125720353","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}

Considering that the deformation manifests anisotropy of the properties of thin wire, the prediction of physical and mechanical properties and the degree of unevenness of deformation becomes an urgent task.The paper studies that an increase in the drawing speed of a thin wire leads to the acquisition of a more uniform and fine‑grained structure. The dependences of the physico‑mechanical properties of thin latuned wire after the metal cord is twisted on the speed of fine drawing are developed. The effect of the deformation rate on the microhardness of a thin steel wire is investigated. It is determined that in order to increase the productivity of metal cord twisting, it is necessary to bring the dependence of the increase in hardness and equivalent stresses in metal cord wires to a linear form by changing the speed of the twisting at its individual stages. For practical use, the dependences of the mechanical properties of a thin wire of strength class HT on the drawing speed are derived.During the analysis, the results were obtained, which are applicable in the design of new or modification of existing routes for drawing thin wire, as well as in the design of new metal cord structures.","PeriodicalId":278844,"journal":{"name":"Litiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115356649","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}

This article describes the experience of producing wire rods made of steel grade Sv‑08G2S for the subsequent production of welding wire in the conditions of OJSC “BSW – Management Company of Holding “BMC”. The technology of welding wire production in the conditions of mill 150 has been developed with heat treatment of the produced wire rod to give it the required plasticity and subsequent processing in hardware production into welding wire. With the construction of a new modern small‑grade wire mill 370/150, the developed technology of welding wire production has been improved to obtain maximum plasticity of the initial wire rod in order to exclude all types of additional heat treatment at the hardware conversion due to the choice of a rational chemical composition of steel and the formation of a favorable microstructure of metal. The wire rod obtained as a result of the work has been successfully processed in hardware production into copper‑plated welding wire without additional heat treatment.","PeriodicalId":278844,"journal":{"name":"Litiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124418536","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}
