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。

Abstract

Effects of Cu

Si and Ti on microstructure and properties of Zn-Al alloy which was optimized by orthogonal test were investigated with optical microscopy

scanning electron microscopy

impact testing and so on.The results show that the optimum alloy composition of the Zn-4Al alloy is Zn-4Al-1.25 Cu-0.04Ti

and its impact toughness is 85.5J/cm2.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.
