摘　　要：本文采用Charpy低温冲击试验、常温拉伸试验等力学性能试验方法,研究了不同的热处理工艺参数对高强度马氏体沉淀硬化不锈钢的低温力学性能的影响。并采用金相显微镜、扫描电镜等检测仪器,对金相显微组织、断口形貌进行了分析。总结出了不同低温力学性能要求时的热处理工艺参数,保证了低温机械性能的一次合格率,解决了低温应用时的返修问题,为低温离心压缩机用高强度、耐腐蚀、耐低温材料的应用提供了理论依据。In this paper,the effect of different heat treatment parameters in low temperature mechanical properties of high strength martensitic precipitation hardening stainless steel was researched by the Charpy low temperature impact test,room temperature tensile test and so on,and the microstructure and fracture morphology were analyzed by metallographic microscope and SEM and so on. The heat treatment parameters about requirement of different low-temperature mechanical properties were summarized to ensure the once qualified rate of mechanical properties in low temperature and to solve the repair problem of application in low temperature. The theoretical basis for the application of material with high strength,corrosion resistance and low temperature resistance used to the centrifugal compressor in low temperature was provided.
