In recent years,the technology of designing and optimizing the heat treatment process parameters with the help of computer simulation technology has become more mature,and the numerical simulation technology is of great significance to guide the actual production.In this paper,the constant speed universal drive shaft of a car with 25CrMo4 is taken as the research object,the designed heat treatment process is simulated by Deform finite element software,the orthogonal test method is applied to optimize the process parameters,and then verified by the microhardness test.The results show that the optimal parameter combination is carburization temperature 950℃,carburization time 80 min,quenching temperature 870℃and tempering temperature 175℃.This paper provides a technical reference for the optimization of heat treatment process parameters in engineering.
