摘　　要：从动态金属学的观点考查了县有不同原始显微组织的GG15钢试样在干滑动摩擦磨损过程中发生的硬化和软化行为及其对耐磨性的影响,指出只有抗软化能力软强的材料组织才有稳定优良的磨损性能。The behavior of hardening and softening of steel GCr 15 with different microstructures during dry sliding friction and wear and its effect on wear resistance of the steel were studied on the basis of dynamic metaUographic analysis. The results indicate that anti-softening microstructure exhibits a rather better wear resistance.
