Abstract: Squeeze casting process was carried out on an industrial 2017A aluminium alloy conventionally used for wrought products. In this research, the effects of applied pressure and die temperature on the microstructure and mechanical properties were investigated. The results show that the finer microstructure was achieved through the squeeze casting. Furthermore, higher pressures improved the fracture properties and decreased the percentage of porosity of the cast alloy. It was found that a direct squeeze casting pressure and die temperature gave a good combination of tensile strength, yield strength and elongation.

Keywords: squeeze casting; pressure; die temperature; aluminium alloys; microstructure; mechanical properties; fracture; porosity; tensile strength; yield strength; elongation.
