EFFECTS OF HIGH-DENSITY CURRENT PULSES ON WORK HARDENING BEHAVIORS OF AUSTENITE STAINLESS STEEL IN WIRE-DRAWING DEFORMATION

. IntroductionThe influence of highdensity pulsing current on the plastic deformation of metals hasattracted much attention in the wo.ld1--14]. Scientists have studied the effects in Zn, Cd,Cu, Fe, W and stainless steel. It has been fOund that when concurrellt application of pulsingcurrent in plastic deformation the fiow stress of metal materials can be reduced2I1o--14],the fatigue life can be increased3], the amount of inner cracks can be reducedl8]. Now thephenomena of the flow stress …
