摘要

The critical temperatures, such as A_c1, A_c3 and M_s of a 65MnCr steel were determined by means of dilatometry on a DIL805A dilatometer combined with microstructure observation and hardness measurement. The continuous cooling transformation (CCT) curves of under-cooled austenite of the 65MnCr steel were obtained. The continuous cooling phase transformation behaviour of under-cooled austenite was studied, and the CCT curves of the 65MnCr steel and 65Mn steel were compared. The results show that the CCT curve of the 65MnCr steel is greatly shifted to the right, and its hardenability is significantly increased compared with that of the 65Mn steel. The critical cooling rate of the 65MnCr steel is recommended in the range of 1℃/s to 3℃/s. The optimum quenching parameters for the steel are obtained: The critical quenching rate is 3℃/s, and the stack cooling temperature is in the range of 200-400℃.
