摘　　要：研究了稀土元素对 9Cr2 Mo钢组织和性能的影响。试验结果表明 :9Cr2 Mo钢中添加稀土元素 ,可使其奥氏体晶粒细化 ,未溶碳化物数量增加 。Effect of RE elements on structure and properties of steel 9Cr2Mo is investigated in this paper The experimental results show that the austenite grains can be refined and the residual carbides can be increased by adding RE elements Therefore, the quenching crack resistance and the tempering stability can be improved
