采用金相和电镜等手段对稀土在高Ｎｉ－Ｃｒ铸铁中的行为进行了研究。结果表明：稀土可以改善高Ｎｉ－Ｃｒ铸铁石墨的形态及分布，使之由长条状向短厚状过渡。并且随着稀土加入量增多，石墨数量增加。
The behavior of rare earth in high Ni-Cr cast iron was studied by means of metallography and electron microscopy. The results show that rare earth can improve the morphology and distribution of high Ni-Cr cast iron graphite and make it transition from long strip to short strip. And with the addition of rare earth increases, the amount of graphite increases.
