结果表明，气孔对高压铸件缩松缺陷的形成有促进作用。气孔中的空气是一种有效的绝热介质，与没有孔隙的区域相比，其阻碍熔体中的热传递，导致较低的局部凝固速率，这可能导致收缩孔隙形成。(c)2006 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
It is shown that gas pores can facilitate formation of shrinkage porosity in high-pressure die-castings. Air in the gas pores is an efficient heat-insulating medium that retards heat transfer in the melt as compared to regions without porosity, leading to lower local solidification rate, which can induce shrinkage porosity formation.
