摘　　要：针对Zn Al系和ZAS35合金设计了一种新的熔体热处理工艺并进行了工艺试验。结果表明 ,合金液的最佳过热温度为 810℃～ 830℃。通过该工艺处理后 ,Zn Al系合金室温组织细化、均匀 ,富锌 β相增多 ,钝化了锌合金中的枝晶 ;ZAS35合金在强度提高的基础上 ,伸长率提高一倍以上 ,冲击韧度提高 5 0A new melting heat treatment process was designed for Zn-Al series alloy and ZAS 35 alloy, and the process test was carried out. The results show that the most suitable temperature range for melting-alloy is 810℃～830℃. After melting heat-treatment, the microstructures of Zn-Al series alloy are refined and uniformed, the quantity of rich-Zn β phase is increased, and the dendritic crystal is passivated.While for ZAS35 alloy, the strength is increased greatly, the elongation is increased by 100%, and the toughness is increased by 50%.
