压铸锌合金性能的老化现象,与所含杂质(如Pb,Sn,Cd)及合金在常温下的相变有关。曾取三种压铸锌合金〔Zn-4Al-0.05Mg,Zn-4Al-2.7Cu-0.05Mg和Zn-4Al-1Cu-0.05Mg〕,观察不同含Pb量对长期时效后合金性能的影响。
The aging behavior of die-cast zinc alloys is related to the impurities (such as Pb, Sn, Cd) and the phase transition of alloys at room temperature. Three kinds of die-cast zinc alloys [Zn-4Al-0.05Mg, Zn-4Al-2.7Cu-0.05Mg and Zn-4Al-1Cu-0.05Mg] were used to investigate the effect of Pb content on the properties of the alloy after long-
