Автоволны локализованной деформации, индуцированной фазовым превращением

Abstract

An approach and a model for the nucleation and development of deformation bands and their fronts during plastic deformation due to phase transformation are proposed. A solid is considered as an open nonequilibrium system, the relaxation of which is determined by both vibrational and electronic degrees of freedom. Electronic transitions between different states of a system of nuclei and electrons upon deformation initiate the excitation of an unstable vibrational mode of atomic displacement to positions characteristic of the martensite phase.
