摘　　要：运用相律和相图基本知识分析了三元相图中特殊点的冷却过程 ..位于晶相组成点连线上的原始组成点 ,其冷却析晶的最终产物为该组成点所在连线两端所代表的晶相 ;位于界线上的组成点和位于无变量点上的组成点 。This paper analyzed the cooling crystallization of special points in ternary phase diagram on the basis of law of phase and elementary knowledge of phase diagram.For the primitive compositional point located on the line connecting crystallization phase compositional points,its end product of cooling crystallization is the crystal phase represented by the two ends of the line on which the compositional point is.For compositional point located on the place of boundary line and non_variable points,its end product of cooling crystallization is the crystal phase represented by the three top points of a sub_triangular on which the primitive compositional points are.

关 键 词：三元相图 特殊点 冷却析晶
