摘要
研究了稀土元素对高铬铸铁中碳化物的影响，并对加稀土、不加稀土的高铬铸铁试样的连续冷却转变（ＣＣＴ）曲线进行了测定。结果表明，稀土元素能破碎高铬铸铁中的碳化物，使碳化物由网状、长条状向岛状、块状过渡。同时，稀土元素提高了高铬铸铁的固态相变温度并缩短了贝氏体的孕育期。
The effect of rare earth elements on carbide of high Cr cast iron was investigated and the continuous cooling transformation(CCT) curves of high Cr cast iron containing and not containing RE addition were determined. The experimental results show that the carbides in high Cr cast iron can be refined and changed from net and long shapes into island and block ones. The phase transformation temperature of high Cr cast iron is increased and incubation period of bainit transformation is lowered.
