摘　　要：运用正交试验方法和回归分析研究了37Cr Mn Mo钢热处理工艺参数与力学性能的关系。结果表明,影响材料力学性能的主次因素顺序为:回火温度>回火时间>淬火保温时间>淬火温度。通过回归分析得出材料力学性能和热处理工艺参数之间的关系,并获得最优工艺参数为淬火温度890℃,淬火保温时间50 min,回火温度580℃,回火时间60 min。经试验验证,优化后的热处理工艺使材料力学性能得到较大提高。回归值与实测值吻合较好。The orthogonal test method was used to study the relationship between the heat treatment parameters of 37CrMnMo and its mechanical properties. The results show that the primary and secondary factors affecting material mechanical properties are as follows： tempering temperature, tempering time, quenching holding time and quenching temperature. The relationship between mechanical properties and heat treatment parameters are obtained by regression analysis.The optimal process parameters are quenching temperature of 890℃, quenching holding time of 50 min, tempering temperature of 580℃, and tempering time of 60 rain. By experiments, the optimized heat treatment process acquires better mechanical properties. The regression results are coincided with the measured values.
