Abstract

In the process of manufacturing parts by plastic deformation, the shape and orientation of the grains of the metallic material changes. The emerging mechanical texture causes anisotropy of the mechanical properties of the material. On the basis of the analysis of the interaction of grains at the microlevel, equations of state are obtained that describe the mechanical properties of the material in a wide temperature-speed range under the action of alternating loads, the superplasticity state, and the Bauschinger effect. The knowledge of the anisotropy introduced by the technology of manufacturing the part is necessary for a numerical analysis of the residual mechanical properties of the parts.
