It is found experimentally that the plastic deformation would localize on the macro-scale level, which involves generation of auto-waves whose type is determined by the acting law of work hardening. By addressing the localized plasticity auto-waves occurring in a solid under constant-rate loading, we have invoked the concept of self-organization to account for a change in the defect structure of the deforming medium. Thus the plastically deforming medium would undergo a change of state due to the concerted redistribution of elastic stresses and to the motion of localized plasticity nuclei emergent at all the flow stages. The former process is controlled by the sound rate and the latter, by the auto-wave velocity. The above suggests that the microscopic characteristics of the crystal lattice are related to the macroscopic characteristics of the localized plastic flow, with the spatial scales being in the ratio l/rion » 108.
