摘　　要：在钢轨钢中加入铬和稀土元素,通过金相显微镜、扫描电镜检验观察其夹杂物、组织,研究新一代稀土钢轨的冲击韧性,耐磨性和耐腐蚀性。实验结果表明,新一代稀土钢轨改善了夹杂物形态,提高了冲击韧性,改善耐磨和耐腐蚀性。Effects of rare earth on impact toughness, wear resistance and corrosion resistance of a new generation of rail steel have been studied by observing inclusion and structure with metallograph and scanning electron microscepe. The results show.that rare earth can improve inclusion shape, impact toughness, wear resistanee and corrosion resistance of the new steel raft.
