摘要(Abstract)：

针对中碳Si-Mn系贝氏体/马氏体复相钢,比较不同热处理工艺(正火+回火,等温淬火+回火)后的组织和性能,以探索适宜的热处理工艺,并进行摩擦磨损实验。结果表明,在本研究范围内,复相钢最佳的热处理方案及相应的性能为950℃×1 h正火+250℃×2.5 h回火,洛氏硬度为51.7 HRC,冲击韧度αK为20.6 J/cm2,抗拉强度为1731.7 MPa;950℃×1 h奥氏体化+320℃×1h等温淬火+250℃×2.5 h回火,洛氏硬度为50.8 HRC,冲击韧度αK为20.9 J/cm2,抗拉强度为1508.0 MPa。干摩擦或油润滑条件下,复相钢均有较好的耐磨性能,相比而言,正火+回火的复相钢耐磨性更好。
