摘　　要：通过探讨不同淬火温度对A100钢显微组织和力学性能的影响,以找到较优强度与塑性的热处理工艺方案。首先,对A100钢进行不同温度(865℃、875℃、885℃、895℃)的淬火处理,随后进行深冷和回火处理。通过显微组织观察、力学性能测试等方法,分析了不同淬火温度对A100钢显微组织和力学性能的影响。结果表明,在热处理工艺为865℃油淬(1h)+深冷处理(-73℃,1h)+482℃回火(5h)时,A100钢具有最佳的综合力学性能。By exploring the effects of different quenching temperature on the microstructure and mechanical properties of A100 steel,we aim to find the optimal heat treatment process for strength and plasticity.Firstly,A100 steel is subjected to quenching treatment at different temperatures(865℃,875℃,885℃,895℃),followed by deep cooling and tempering treatment.The influence of quenching temperature on the microstructure and mechanical properties of A100 steel was analyzed through methods such as microstructure observation and mechanical property testing.The results show that when the heat treatment process is 865℃oil quenching(1h)+deep cooling treatment(-73℃,1h)+482℃tempering(5h),A100 steel has the best comprehensive mechanical properties.
