摘　　要：采用光学显微镜(OM)、扫描电镜(SEM)、X射线衍射仪(XRD)和硬度计测试了一种高合金耐磨铸铁的组织与硬度。结果表明,该耐磨铸铁铸态组织主要由马氏体、莱氏体、TiC和(Fe-S-Ti-C)化合物组成,具有较高的硬度和抗高温软化性能。The microstructure and hardness of a kind of high alloy wear resistant cast iron were investigated by optical microscopy, scanning electron microscopy, X-ray diffractometry and hardness tester. The results show that the microstructure of the cast wear resistant cast iron is mainly composed of martensite, ledeburite, TiC and （Fe-S-Ti-C） compound, which have higher hardness and high temperature softening resistance.
