| Abstract: | The procedure and several results of experimental studies on the high-density current pulse-induced relaxation of shear stresses are presented. A significant nonthermal current effect on shear strain kinetics has been established. The strain rate of the metal in shear under the action of a current pulse is shown to be determined by the viscosity factor, like under high-rate inelastic deformation.
