The microstructural nomograph of these Al-Si alloys is constructed to provide for the selection of optimum addition of Sr or Sb in production practice Experimental results indicate a threshold of Sr content in Al-Si alloy modification, over it, the structure of Al-Si alloy may be completely modified even at quite slow cooling rate down to 4.5℃/min.

实验结果表明，Al-Si合金加Sr后变质存在一个变质阈值，超过这个阈值时，即便在投缓慢的冷速(4.5℃/min)下，仍能获得完全变质的组织。这个变质阈值随着冷速的减慢而增大。

The intermetallic compounds are coarsened into nubbly Cu6 Sn5 phase by adding excessive Cu into Sn-Cu solder alloy. For Sn-9Zn-xCu solder alloys, the long needle-like Zn rich phase which is the mainly existing form of Zn in Sn-Zn solders is transformed into Cu5 Zn8 phase and fine Zn rich phase by the addition of 2% Cu, while CuZn phase and Cu6 Sn5 phase are formed in Sn-9Zn-10Cu bulk alloy. When soldering within short time under 260℃, the ripening and growth of IMC at Sn-xCu/Cu interface are accelerated with increasing Cu content in Sn-Cu solders.

结果表明，当Sn-Cu钎料中Cu的含量为2%时，基体中IMC粗化为块状的Cu6Sn8相；对于Sn-9Zn-xCu钎料合金，2%Cu元素的加入使得Sn-9Zn基体中长针状的富Zn相转化为Cu5Zn8相以及细小的富Zn相，而当Cu含量达到10％时，钎料基体中的IMC为CuZn相与Cu6Sn5相。
