A technique to heal tensile plastic strain in a stainless steel by controlling high density electric current was developed. The tensile plastic zone before and after electropulsing was observed by optical microscope, and the effect of electropulsing on the recovery of strain in stainless steel was evaluated by digital image correlation method. It was found that the electric stimulation influences the recovery of plastic strain, and the average rate of recovery is 19.3% in stainless steel. The high density electric current treatment makes it possible to retard the failure of materials by healing tensile plastic strain.
