Streszczenie:
A hardening rule accounting for anisotropy produced by plastic deformations is developed. Transition from an initially isotropic material into an anisotropic one is studied. The proposed rule accounts for translation, rotation and expansion of the initial yield locus.

Streszczenie:
The present paper is concerned with the analysis of some cyclic deformation processes aimed at improved metal forming and generation of fine grain structure. Next, the model of microstructure evolution is discussed and the evolution rules are proposed. The shear banding process accompanying the continuing recrystallization is analyzed and the respective constitutive equations are presented.
