The tin inverse segregation was lightened for the SiC skeleton, because tin was gathered in a very narrow region near the surface of skeleton, which avoided tin mass segregation in the surface layer of the cast. 骨架减轻了复合材料中锡的反常偏析,使锡的偏析主要发生在骨架表面附近的微小区域,从而避免了在铸件表层的集中偏析。
In addition, the content of inverse segregation elements ( Si, Ni, Cu) must be limited. 另外,还必须限制反偏析元素Si、Ni、Cu的含量。
The inverse segregation of six ingots could not meet the requirements, and the segregation of the ingots of water-cooled copper mold is more intense. 实验制得的6个铸锭的反偏析程度不能满足使用要求,水冷铜模铸锭偏析程度更为剧烈。
