Na、Sr、Sb、P对铝硅合金致密性的作用

Effects of Na,Sr,Sb,P on the Compactness of Al Si Alloys

研究了ＺＬ１０１，ＺＬ１０２合金的致密性，考察了Ｎａ、Ｓｒ、Ｓｂ、Ｐ变质元素对合金致密性的影响。试验结果表明，ＺＬ１０２合金有较高的致密性，Ｎａ、Ｓｒ使合金的致密性降低，而Ｐ处理能明显提高合金的致密性。分析认为。

The compactness of ZL101 and ZL102 alloys has been studied, and the effects of some modifiers, such as Na,Sr,Sb and P, on the compactness of alloys have been tested. Experimental results show that Na and Sr make the alloy compactness reduce, but P proves the contrary. The compactness of alloys is related to effects of the modifiers on the solidification temperature range of alloys.
