摘　　要：研究电塑性加工技术在冷拔精密合金（３Ｊ５３） 中的应用。发现选择一定的电流脉冲频率可产生显著的电塑性效应。研究结果表明：与普通拔丝工艺相比较，经电塑性拔制后，３Ｊ５３ 合金钢丝的拔制应力相对降低。分析认为。The application of the electro plastic technique in the cold drawing of precious alloy 3J53 is investigated It is first discovered that an apparent electro plastic effect emerges with selecting certain impulse current frequency in cold drawing The investigation results show that the drawing force decreases comparing with the traditional drawing process By the analysis,it is considered that the electro plastic effect has something to do with the changing of the external frictional force in cold drawing
