Abstract:

The influence of electric current on the mechanical properties of metals is reviewed. Included are the effects of both low density approx. 1Asq mm continuous current and high density approx. 1000Asq 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
