亚温淬火对25MnV钢显微组织和力学性能的影响
Effect of Sub-temperature Quenching on Microstructure and Mechanical Properties of 25MnV Steel
摘 要
采用正交组合回归设计试验方法研究了不同温度亚温淬火对25MnV钢抗拉强度和硬度的影响,分析了该钢亚温淬火后的组织.结果表明:25MnV钢经亚温淬火后,得到极细的板条状马氏体组织;830 ℃淬火时,马氏体板条之间分布着条状的铁素体;在810~830 ℃温度范围内,随淬火温度升高,该钢的强度和硬度升高,830 ℃亚温淬火的强度、硬度最好.

Abstract
The effect of sub-temperature quenching at different temperature on the tensile strength and hardness of 25MnV steel was investigated by orthogonal regressive principle.The microstructure of the steel after sub-temperature quenching was analyzed.The results indicate that the very fine lath martensite of 25MnV steel was obtained by sub-temperature quenching.The strip ferrite was distributed between martensite laths as the steel quenched at 830 ℃.In the temperature range of 810 to 830 ℃,the strength and hardness of the steel were increased along with the increasing of the quenching temperature.The best tensile strength and hardness could obtain in 25MnV steel when sub-temperature quenched at 830 ℃.
