The good effect has been gained on the hypereutectic Al Si alloys treated with some double refining and modifying agents such as P, S, RE, Sr, Na, C, etc.

采用磷、硫、稀土、锶、钠、碳等进行双重细化变质处理过共晶铝硅合金已取得了良好的效果。

The modifying elements used in hypoeutectic Al Si alloys, besides Na, there are also Sr, Te, Ba, Sb, K, RE, B, S, etc.

亚共晶铝硅合金的变质元素除钠以外，还有锶、碲、钡、锑、钾、稀土、硼、硫等。其中，应用较多的是含钠和锶的变质剂。
