FIELD: plastic metal working. SUBSTANCE: method comprises steps of deforming blank until stress level exceeded yielding strength of blank material; passing electric current pulses through said blank at maintaining outer load; repeating deformation foe achieving stress level more than previous one by 8-10%; preliminarily setting direction of main stresses in deformed blank; coinciding direction of electric current pulses passing through blank with direction of main stresses of blank material; fixing load value for time period of passing electric current pulses. EFFECT: enhanced efficiency due to lowered resistance of metal against deformation and complete use of metal ductility resource at given load level. 4 dwg
