摘要
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 effect of rare earth(RE) additive on modification of graphite in high Ni-Cr alloy cast iron was investigated by using optical and scanning electron microscope.The experimental results show that the morphology and distribution of graphite in high Ni-Cr alloy cast iron can be improved by adding a certain amount of RE additive.The long stripe graphite can be replaced by short columnar or spherical one and the number of graphite is increased with increase of RE additive.
