摘　　要：研究了不同等温淬火工艺对Cr12MoV钢性能的影响。结果表明,Cr12MoV钢在1020℃奥氏体化后经280℃×3 h等温淬火,能够得到良好性能的M/B下复相组织,与常规淬火相比,在冲击性能不降低的情况下,耐磨性提高显著,其磨损量下降了56%。The influences of austempering process on properties of Cr12MoW steel were studied.The results show that the martensite/bainite dual phase structure of the steel can be obtained by austenizing at 1020 ℃ and then austempering at 280 ℃ holding for 3 h.Compared with normal quenching,the austempering remarkably enhances the wear resistance of the steel with wear loss decreased by 56% while impact toughness is not reduced.
