摘　　要：对奥氏体锰钢进行变质处理,开展了固溶、时效等热处理试验和动载冲击磨损试验,研究了变质和热处理等因素对组织和耐磨性的影响。结果表明:奥氏体锰钢具有应变强化效应,通过变质处理,使铸态组织和晶粒明显细化,组织状态得以改善。奥氏体锰钢经1080℃固溶+250℃时效处理后,可获得较优的显微组织和耐磨性能。The austenitic manganese steel was modified, and the heat treatment tests such as solution and aging and dynamic load impact wear tests were carried out, the influence of deterioration and heat treatment on the microstructure and wear resistance was studied. The results show that the austenitic manganese steel has strain strengthening effect, the cast microstructure and grain size are obviously refined and the microstructure is improved by modification. The better microstructure and wear resistance can be obtained by solid solution treatment at 1080 ℃ and aging treatment at 250 ℃.
