摘　　要：采用高温摩擦磨损试验机及扫描电镜研究了不同成分高强结构钢T700、T520和T610L的耐磨性。结果表明,T700的耐磨性能明显优于T520和T610L。T700含有更多Mn和Ti,可起到固溶强化的作用,增强基体的强度和硬度;Ti能抑制奥氏体的再结晶,使晶粒细化,从而增强材料强度和硬度。The wear resistance of different components high-strength structural steel T700, T520 and T610L was studied by high-temperature friction and wear tester and SEM. The results show that the wear resistance of T700 is better than T520 and T610L. The component analysis founds that T700 containing more Mn and Ti, Mn element can make an appreciable solid solution strengthening, and the strength and hardness of the material can be enhanced. Ti element can suppress the recrystallization of austenite and grain refinement, enhance the strength and hardness of the material.
