摘　　要：研究了微量铬对高速车轮钢组织和性能的影响。实验结果显示,加入微量的铬,可以细化珠光体的片层间距,在保持韧塑性基本不变的情况下,显著增加材料的强度和硬度,从而提高车轮钢的耐磨性和抗剥离性能。The effect of microalloy element on the microstructure and mechanical properties of high-speed wheel steel was studied. The results show that small Cr addition in steel can decrease the lamellar spacing of pearlite, and markedly increase strength and hardness with almost the same ductility and toughness, and accordingly improve wear and shelling-resistance of wheel steel.

关 键 词：车轮钢 铬 硬度 片层间距
