Influence of Heat Treatment for the Microstructure in GCr15 Bearing steel

摘要：

　　The influence of microstructure in GCrl5 bearing steel by the different heat treatment conditions was studied,and the influence regular pattern of recrystallization percentage in GCr15 bearing steel by the different deformation amount,deformation temperature and dwell time after rolling was also analyzed.The research results show that when the deformation temperature and deformation amount under certain conditions,the recrystallization percentage of deformed austenite in GCrl5 bearing steel increases as the dwell time after rolling increases,and the austenitic grain is also grow up; The uniformity of deformed austenite organization is influenced greatly by the different deformation amount,deformation temperature and dwell time after rolling,when the deformation temperature is 950 ℃,the deformation amount is 45% and the dwell time after rolling is 100 S,the recrystallization percentage can up to 84.57%.
