摘要

In this study the literature related to Zinc-Aluminium cast alloy was reviewed and discussed. Few works have been published on the effect of Copper addition on the mechanical behaviour, hardness, and microstructure of the obtained alloys. The effect of 4% Cu addition to Zn-21Al on the mechanical behaviour and microhardness was investigated. It was found that the addition of 4% Cu resulted in 18.3% enhancement in microhardness where the mechanical characteristics were reduced (softening) by 14.5% at 0.2 strain. It has been found that after upsetting test, the microhardness was enhanced by 53.3 % and 42.7 % for Zn-21Al and Zn-21Al-4%Cu respectively.
