Abstract
A direct (nonthermal) high-density pulse current effect on the plastic strain rate in the metal under loading and on the relaxation of elastic stresses in it is evaluated. The evaluation is based on existing notions of electronic conductivity and thermally activated dislocation motion-controlled plastic strain mechanisms in metals. The effect of pulse current on the plastic strain rate is shown to become more and more pronounced with current density, elastic stress levels, and temperature; at low current densities and applied loads its effect is inessential.
