The paper presents the results of experimental examination of material deformed state in the process of realization of its mechanical processing (drawing with thinning). In particular, the new effect were revealed, which were not presented before in the literature; these effects have influence on final deformation forming, especially in the process dynamics. The results of evolution of the material mechanical properties in various cross-sections of semiproducts are presented, accompanied with assessment of their heterogeneity, of microstructure and chemical composition of the alloy after plastic deformation. The ways of further development of researched effects and the factors determining these effects (such as friction and work tool geometry) are suggested.

The research was carried out under financial support of the RF Ministry of Science and Higher Education (Scientific and research work “Study and prediction of gradient strength fields and plastic parameters of metals in cold metal forming processes with complicated loading”, FZWF-2024-0006).
