Abstract
Results of experimental evaluation of the pulse current effect on stress levels in a stretched steel strip are presented. At the stage of growing loads, stress relaxation in the strip is shown to increase with current densities and loads. After a stepwise decrease in loads, pulse current passage causes an increase in tensile stresses rather than their relaxation. It was suggested that loading and further unloading result in microplastic strains of different directions, which become apparent upon pulse current passage. The phenomenological model of the metal behavior describing the pulse current effect upon loading and unloading is proposed.
