摘　　要：研究了热处理工艺对55SiMoV钢组织、力学性能及多冲抗力的影响。研究结果表明，该钢淬火后，随奥氏体化温度升高，晶粒变粗，板条尺寸增大，孪晶数量增多。获得最佳综合力学性能的工艺为：870℃淬火＋200～220℃回火。The influence of heat treating process on the mechanical properties and microstructure of 55SiMoV steel has been studied in this paper. The results show: with the increasing of austenitizing temperature, prior austenite grain and matensite lath become coarse, the amount of twin increasing. Optimizing process for mechanical properties is that austenitizing temperature: 870℃,tempering temperature 200℃~ 220℃.
