Abstract
Propagation velocity and dispersion of autowaves of localized plastic deformation have been considered at the stages of easy slip and linear strain hardening in some pure metals and alloys. The quadratic form of the dispersion relation and the dependences of the phase and group velocities of autowaves on the wave number have been found and explained. The relationship between the characteristics of the autowaves of localized plastic flow and the parameters of elastic waves in materials has been established. A quantity that is invariant for the processes of elastic and plastic deformation. The change in the entropy of the system upon the generation of autowaves of localized plastic flow has been estimated.
