摘要
RE inclusions formed during the solidification of molten steel was studied with TEM and SEM.The results show that with increasing of the ratio of sulphur to oxygen, the reaction products of RE with sulphur and oxygen will be successively RE2O3, composites of RE2O3 and RE2O2S, RE2S3, and a few particles of REO2.
