Experimental Investigation of Squeeze cast Aluminium 2024/Zn alloy using Taguchi method

Casting is a manufacturing process where a metal is heated to a proper temperature and is then poured into a mold or cavity which contains it in the proper shape during solidification. In this experimental work investigation has been performed on Squeeze casting of Aluminium 2024 and Zinc alloy. The effect of squeeze casting parameters like different weight percentage of zinc and squeeze time has been investigated the relationship between tensile strength, micro-hardness and corrosion of the casted sample. Aluminium 2024 is taken as a base material and Zinc is taken as a alloy material. Different weight percentage of Zinc of 4% and 5% and Squeeze time of 10 min and 15 min are taken for the study. Taguchi L4 orthogonal array is employed for the experimental design. Finally, analysis of variance (ANOVA) is performed to know the impact of individual factors on tensile strength, hardness and corrosion resistance. It is observed that the weight percentage of zinc is the most influenced parameters. Multiple regression equation is formed for estimated predicted values of tensile strength, micro-hardness and corrosion resistance. As a conclusion, it has been derived that the weight percentage of zinc provide better hardness and corrosion resistance and squeeze time influence tensile strength of the samples for the given experimental conditions.
