摘　　要：分析了耐磨钢铁中奥氏体、马氏体、碳化物的结构和作用，介绍了奥氏体钢、马氏体钢和抗磨白口铸铁的应用情况。指出相同化学成分的耐磨钢铁，由于热处理工艺不同，得到不同的显微组织，致使材料的力学性能、抗磨损性能、耐热耐蚀性能相差甚多，显微组织决定耐磨钢铁材料的性能。The structure and function of austenite, martensite and carbide in wear resisting cast steel and iron were analyzed. The applications of austenite steel, martensite steel and abrasion resistant white cast iron were presented. Due to the different heat treatment process, the wear resisting cast steel and iron with the same chemical composition might get the different microstructure. Thus the mechanical properties, wear resistance, heat and corrosion resistance of the materials can vary a lot. Microstructure decides to the performance of wear resisting cast steel and iron.
