摘　　要：通过单因素实验法设计不同热处理工艺,并对热处理后的国产M5合金的显微组织和力学性能进行研究。结果表明:国产M5合金经β相淬火后组织为马氏体组织;淬火温度对国产M5合金的晶粒尺寸、抗拉强度和屈服强度影响较大,回火温度和回火时间对国产M5合金的塑性影响较大。综合考虑确定920℃淬火+610℃真空回火8 h为最优热处理参数。The different heat treatment processes were designed through single argument method, and the microstructure and mechanical properties of M5 zirconium alloy after heat treatment were studied. The results show that the microstructure after β phase hardening is martensite. The quenching temperature has big effect on grain size, tensile strength and yield strength of M5 zirconium alloys. The tempering temperature and time has big effects on plastic property of the alloy. Quenching at 920℃ and tempering at 610℃ for 8 h is tested to be the best combination parameters.
