Abstract

One binary Zn-40Al and four ternary Zn-40Al-(1, 2, 3, 4) Cu alloys were produced by permanent mould casting at different pouring and mould temperatures. Cooling curves were obtained, and the average cooling rate for each alloy ingot was determined. The hardness, tensile strength, percentage elongation and impact energy of the alloys were measured after studying their microstructure by optical and electron microscopy. The effects of cooling rate and copper content on the structure and mechanical properties of the alloys were investigated.
