研究了超高锰钢铸态和热处理态的显微组织、力学性能和耐冲击磨料磨损性能。结果表明，超高锰钢水韧后的组织为奥氏作基体上弥散分布有细小的碳化物颗粒和球形夹杂；变质处理使组织中的碳化物颗粒细化，且分布更加均匀弥散；在0．5J的磨损冲击功下，Mn20（S）和Mn17（SR）的耐磨性分别比Mn12（SR）提高50％和28％以上；在1．0J的磨损冲击功下，Mn17（SR）的耐磨性比Mn12提高40％以上。
The microstructure, mechanical properties and wear resistance of impact-resistant abrasive in as-cast and heat-treated super high manganese steel were studied. The results show that the microstructure of the ultra-high manganese steel after the austenite is finely dispersed carbide grains and spherical inclusions dispersed on the matrix; metamorphic treatment to make the organization of carbide particles refinement, and the distribution more uniform dispersion; 5J wear impact energy, Mn20 (S) and Mn17 (SR) wear resistance than Mn12 (SR) increased by 50% and 28%; wear impact energy of 1.0J, Mn17 Grinding more than 40% more than Mn12.
