用磷铜合金和四元钠盐变质剂对过共晶铝硅合金进行了变质处理试验。结果表明:磷一钠联合变质,能使初晶硅和共晶硅同时细化,但变质效果不甚稳定。
Phosphor copper alloy and quaternary sodium salt modifier of hypereutectic Al-Si alloy modification test. The results show that the combination of phosphorus monosodium and metamorphism can make the primary silicon and eutectic silicon refine at the same time, but the metamorphic effect is not stable.
