摘　　要：对ZGMn13Cr2钢和Fe-13Mn-xAl-C(x=3、5)系轻质高锰钢在0.5、1.0、2.0和4.0 J冲击功下的磨损性能进行了研究分析,并借助光学显微镜(OM)和扫描电镜(SEM)对钢的微观组织和冲击磨损表面形貌进行了观察分析.结果表明:在0.5 J冲击功下,轻质高锰钢的耐磨性最好,相较于ZGMn13Cr2钢,Fe-13Mn-3Al-C钢的耐磨性提高4.39倍,Fe-13Mn-5Al-C钢的耐磨性提高3.83倍;在低应力(0.5 J)状态下ZGMn13Cr2钢和Fe-13Mn-xAl-C(x=3、5)系轻质高锰钢主要以显微切削为主;在高应力(4.0 J)状态下,磨损机制主要以疲劳剥落为主.The wear properties of ZGMn13Cr2 steel and Fe-13Mn-xAl-C（x=3, 5） high manganese steel under impact energy of 0.5 J, 1.0 J, 2.0 J and 4.0J were investigated. By using optical microscopy and scanning electron microscopy,the influences of microstructure and impact on morphology of worn steel surface were observed and analyzed. The results show that the wear resistances of Fe-13Mn-3Al-C and Fe-13Mn-5Al-C high manganese steels at 0.5 J were 4.39 times and 3.82 times that of ZGMn13Cr2, respectively. The wear mechanisms of ZGMn13Cr2 steel and Fe-13Mn-xAlC（x=3, 5） of high manganese steel were mainly micro-cutting under low stress（0.5 J）. Under the impact energy of 4.0 J,the wear mechanism was fatigue peeling
