摘　　要：对Ａｌｓｉ９Ｃｕ３合金中气孔的形成与压铸工艺、结晶时间和冷却速度、氢会计师、合金成分、变质剂和除气方法等之间的关系进行了研究，并分析了各影响因素对气孔的作用机理。The relationship between the porosity formation and various influence factors such as die - casting process, solidification time, cooling rate, hydrogen content, alloying constituent, modificater, degassing method, etc. in an AlSigCu3 alloy is studied. The function mechanisms of different influence factors are also analysed.
