摘要
以汽车分动器链条总成用超高强度钢50CrNiMoVA作为研究对象,通过不同工艺的等温淬火工艺验证和金相分析,考察了淬火温度的变化对材料显微组织和力学性能的影响,并在此基础上得出了该钢种的最佳热处理工艺。结果表明,采用910℃加热+320℃盐浴等温淬火工艺,明显改善了钢的强韧性。
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.
