摘要
研究了不同含硫量和不同冷却速度下铈、镧和钕对铸铁石墨形态和基体组织的影响。试验表明，不同的稀土元素在铸铁中的行为是不一样的。同时，硫和冷却速度对稀土元素的作用有重要的影响。
In this paper,effects of Ce,La and Nd on graphite morphology and matrix structure in cast iron with various sulphur content and under various cooling rate have been studied. Results show that behaviour of various rare earth elements in cast iron is different ,morecover sulphur and cooling rate influence substantially the role of rare earth in cast iron.
