Abstract

The objective of this research is to optimize the process parameters of stir casting by Taguchi method for maximizing the hardness of Al-SiC composites. Composite materials used Al-Si alloy as matrix and SiC (silicon carbide) particles of 400 mesh size as reinforcement agent. Experimental parameters were SiC content, melting temperature of the matrix, rotation speed and stirring time duration, and each parameter using 4 levels or variations. Experimental design used L16 orthogonal arrays of Taguchi method standards. The hardness of Al-SiC composites were tested by Brinell hardness test. The microstructures of Al-SiC composite were observed by scanning electron microscopy (SEM). Experimental results show that the optimum of process parameters of stir casting are SiC content of 15 % (wt.), melting temperature of 740 oC, rotation speed of 100 rpm (round per minute) and
stirring time duration of 20 minutes. The most significant factor affected onthe hardness of Al-SiC composite is SiC content with contribution of 70.72%.
