【Abstract】 The effect of high-density current pulses on wire drawing of a HoCr17Ni6Mn3 steel was investigated at room temperature. It was found that the wire drawing force was obviously reduced by application of pulse current and the largest decreasing amount is about 40%, indicating that the electroplastic effect is obvious. It was also found that by the use of pulse current, the deformation ability of the wires is increased greatly afid the work hardening rates of the wires is apparently decreased. With high-density current pulses, the wire of original diameter of 2.0 mm was drawn to that of 0.255 mm without any heat-treatment. The ultimate tensile stress of as-drawn wires decreases by drawing withcurrent pulses.更多还原
