摘要：

Results of a study of the effect of hot deformation under isothermal conditions under bicomponent (twisting + stretching) proportional loading with various ratios of the axial and shear components of the deformation on the mechanical behavior and evolution of the initial coarse lamellar microstructure and crystallographic texture in alloy VT9 are presented. It is shown that the ratio of the axial and shear components of the deformation is responsible for the degree of localization of plastic yield of the material and the fullness and intensity of transformation of the lamellar microstructure into a globular microcrystalline microstructure in the functional zone of deformed specimens.
