分析制定了60Si2CrVAT弹簧钢合理的热处理制度,利用正交实验极差分析的方法并结合金相及回火后析出相的分析,研究了热处理工艺参数对60Si2CrVAT弹簧钢力学性能的影响,确定了其最佳热处理工艺。结果表明,回火温度和回火时间对强度的影响较大,回火温度和淬火保温时间对塑性影响较大,60Si2CrVAT弹簧钢最佳热处理工艺为：（900℃＋25 min）油淬＋（400℃＋40 min）回火,水冷。
Heat treatment processes with different processing parameters for 60Si2CrVAT spring steel were designed based on metallurgical principle,and the influence of heat treatment parameters on microstructure and mechanical properties of 60Si2CrVAT spring steel was studied by means of optical microscopy,orthogonal experiments and tensile tests.The heat treatment process was optimized based on the investigation.The results show the relatively significant effect of tempering temperature and tempering time on strength is observed,while tempering temperature and holding time exhibits larger effect on plasticity.The optimum heat treatment process is quenching at 900 ℃ for 25 min in oil and tempering at 400 ℃ for 40 min and then cooling in water for 60Si2CrVAT spring steel.
