Abstract: The structure of a two-component model of localized plasticity and the scenario of the birth of macroscopic scales of plastic flow within its framework are considered. The mechanism of the emergence of a macroscopic autowave scale during the development of plastic deformation is proposed and quantitatively substantiated. The conditions for the stratification of a deformable medium into dynamic and information subsystems are described and their roles in the formation of macroscopic scales of the order of the length of the autowave of localized plasticity are analyzed. The nature of the relationship between the emergence of a macroscopic scale during plastic flow and the elastic-plastic invariant of deformation, previously established experimentally, is explained.

Keywords: deformation, plasticity, localization, model, scale, self-organization.
