摘要
通过在冷轧辊用９Ｃｒ２Ｍｏ钢中添加稀土元素，利用全自动膨胀仪研究了稀土元素对其抗回火能力的影响．试验结果证明，稀土元素对钢中碳化物的结构没有影响，但抑制了碳化物的析出过程，提高了其抗回火能力．
The effect of rare earch elements on tempering stability of cold roller steel 9Cr2Mohas been investigated by means of full automatic transformation recording-measuring instrument.The experimental result shows that RE elements has no effect on carbide structure, but the process of carbide precitation can be restrained. So that the tempering resistance of this steel can beincreased.
