摘　　要：用钛对Cr12MoV钢进行了变质处理。采用金相显微镜、扫描电子显微镜研究了钢的微观组织,采用冲击试验机测试了钢的冲击韧性。研究结果表明:变质处理后,铸造Cr12MoV钢中碳化物的分布得到改善,冲击韧性提高了1.4倍。Cast Crl2MoV steel was modified by using Ti. The microstructures of cast Crl2MoV steel was investigated by metallurgical microscope and scanning electron microscope （SEM）. The impact toughness was tested by impact testing machine. The results show that, after modification, the carbides distribution in cast Crl2MoV steel is improved and impact toughness is increased by 1.4 times.

关 键 词：CR12MOV钢 变质处理 冲击韧性
