The influence of stepwise deformation of aluminum–magnesium alloy upon its electrical conduction

Abstract

The influence of stepwise deformation upon the electrical conduction of the AlMg6 aluminum–magnesium alloy is investigated experimentally. It is found that the nucleation and development of single deformation bands causing stepwise deformation increase the specific electric resistance of the alloy on average by 2–3%. It is supposed that the main mechanism of an increase in the electric resistance in the deformation band is growth of the deformation vacancy concentration, which is connected with intensive dislocation multiplication in the deformation band front.
