介绍一种以稀土、钒、钛复合变质处理的新型超高锰耐磨铸钢，研究表明该材质在一定的固溶温度、冷却方式、保温时间及时效强化工艺条件下，能获得单一奥氏体基体上弥散分布着均匀、细小的球状碳化物理想金相显微组织，各项力学性能指标优异，可适用于各种高低应力的工况条件。 A new ultrahigh manganese wear-resistant cast steel treated with rare earth, vanadium and titanium was introduced. The results show that under certain solid solution temperature, cooling method, holding time and aging strengthening process, On the matrix, the microscopic microstructure of even and fine globular carbide is dispersed and distributed. The mechanical properties of the microstructure are excellent and can be applied to various working conditions of high and low stress.
