Abstract: The relationships between macroscopic and microscopic deformation methods are considered using comparative characteristics of dislocation systems and the nature of dispersion of localized plasticity autowaves for different stages of the deformation curve. It is established that the form of the dispersion law for each stage of strain hardening is determined by good dislocation ensembles that arise at different stages of the plastic deformation process.

Keywords: plasticity, localization, dislocations, autowaves, dispersion.
