摘要
研究了近２０种简单和复杂二元共晶合金在强磁场搅拌下形成分离共晶的现象．发现大多数金属／非金属类共晶和部分金属／金属间化合物类共晶发生分离共晶现象，其判据可定为分离相的熔解熵△Ｓ≥２３Ｊ／（ｍｏｌ·Ｋ）．
The separated eutectic for nearly 20 kinds of simple and complex eutectic alloys was investigated. It shows that most metal-nonmetal eutectic and a part of metal-intemietallic compound eutectic were separated by electromagnetic stirring. The eutectic in which one of its component phases possesses an entropy of solution over 23 J/(mol. K) shows noted separation.
