摘　　要：提出了一个均匀化处理的新观点,指出少量液体的存在可从几个方面促进GH169合金均匀化过程,从而可使Laves相消除的时间大大缩短。叙述了有少量液体存在时Laves相消除的微观过程。A new point of view on the homogenization treatment has been pro- posed. It is supposed that a little liguid in the alloy may promote the homogenization process in some aspects and reduce the time for eliminating the laves-phase in alloy GH169. The microprocess of the elimination of Laves-phase in the case of a little liguid existing in the alloy has also been described.
