除了传统的用钠变质处理外,人们还可以用加锑的方法来改变Al—Si合金的组织。这两种处理导致了不同的金相显微组织(如图1和图2)。 众所周知,这两种处理是不相容的,锑的存在会妨碍钠的变质作用。
In addition to the traditional sodium modification, one can also use antimony method to change the Al-Si alloy organization. Both treatments result in different metallographic microstructures (Figure 1 and Figure 2). It is well-known that the two treatments are incompatible and the presence of antimony can hinder the metamorphism of sodium.
