Abstract
The set of physical effects — the electron wind, the dynamic pinch effect, the change of the interaction energy of dislocations with local pinning sites, the presence of an electric current and a magnetic field, dynamic thermoelastic stress, strong effects of the heat flow on the carriers of plastic deformation — which lead to additional electroplastic deformation with the passage of a high-density pulsed electric current through a metal is treated. Estimates of the magnitudes of these effects are given. The idea of dynamic nonequilibrium dislocation ensembles which permit a phenomenological description of the effect of an electric current on the plastic deformation of metallic materials is noted.
