| Abstract: | Taking the high strength steel 50CrNiMoVA used in the chain of the automotive sub-actuator as the study object,using different processes of austempering process validation and metallographic analysis,the quenching temperature effect on the material microstructure and mechanical property are investigated.On this basis,the best heat treatment process of the steel is obtained.The results show that,using 910℃ heating and 320℃ salt bath austempering process,the strength and toughness is significantly improved. |
