摘　　要：通过正交试验方法,利用金相显微镜、扫描电镜、冲击试验等研究了Cu、Si、Ti对锌铝合金组织与性能的影响,确定了优化成分。结果表明,Zn-4Al合金最优化的成分为Zn-4Al-1.25Cu-0.04Ti,其冲击韧度为85.5J/cm2。Zn-Al合金的共晶组织耐冲击性能最差;Si严重降低冲击性能,Ti和Cu都可以细化合金组织和提高力学性能。Effects of Cu, Si by orthogonal test were in ting and so on. The result and Ti on microstructure and properties of Zn-A1 alloy which was optimized vestigated with optical microscopy, scanning electron microscopy, impact tess show that the optimum alloy composition of the Zn-4Al alloy is Zn-4Al-1.25 Cu-0.04Ti, and its impact toughness is 85.5 J/cm^2. The Zn-Al eutectic alloy has the worst impact resistance. Si addition can deteriorate seriously the impact properties. Ti and Cu can refine the microstructure in the Zn alloy and improve the mechanical properties.
