The Electroplastic Effect in Metals.

Abstract

The influence of electric current on the mechanical properties of metals is reviewed. Included are the effects of both low density approx. 1A/sq mm continuous current and high density approx. (1000A/sq mm) current pulses, with special attention given to the latter. The influence of the parameters involved in the thermally-activated overcoming of short-range obstacles to dislocation motion. Considered are: (a) the force drift electrons exert on dislocations held up at obstacles and (b) the influence of drift electrons on the obstacle strength and on the pre-exponential factor. (Author)
