The effect of a single pulse of electric current on the mechanical property of advanced high strength steels (AHSS) under quasi-static tensile loads is investigated by experiments. During a typical quasi-static tensile test, electric current is applied to a specimen for a short duration (less than 1 second) while the specimen is in plastic region. The stress-strain curve shows that the flow stress almost instantly decreases significantly (stress-drop) when the electric current is applied, while the tensile strength from the following stress-strain curve after the short pulse of electric current is not changed much. The experimental result suggests that the stress-drop at the moment of a short pulse of electric current can be effectively used to reduce the springback of material, as successfully demonstrated in the present study.
