Within the framework of a two-component model of plastic flow using thermal activation analysis of the kinetics of elementary acts of plastic deformation, the cause is determined and the conditions for the birth of a macroscopic (autowave) scale during the development of localized plastic flow are analyzed. On this basis, the nature of the elastic-plastic invariant of plastic flow, which links the characteristics of the elastic and plastic components of material deformation, is explained. Keywords: plastic deformation, localization, invariant, thermally activated processes, autowaves.
