摘　　要：采用正交试验法对40Cr钢进行了脉冲电场作用下的研究,找出了降低40Cr钢淬火加热温度和缩短保温时间的工艺参数,且其硬度比常规淬火高2～3 HRC。进行了相应的新工艺试验,得到了40Cr钢较理想的马氏体组织,改善了40Cr钢的淬火组织和机械性能,提高了工作效率,降低了成本。By applying the method of orthogonal trials,the research of 40Cr steel under pulse electric field is carried out and the parameters which could reduce the quenching temperature and holding time are found.With these parameters,the hardness of 40Cr steel is improved by 2～3 HRC.By carrying out new process experiment,the ideal martensite organization is required which improves the mechanical properties and production efficiency.

关 键 词：脉冲电场 40CR钢 淬火
