Optimizing Mechanical Properties of Metal Matrix Composites Using Taguchi’s Technique

Aezeden Mohamed and Noel Martin


AA6162 alloy belongs to the Al 6000 series, renowned for its outstanding corrosion resistance and strength properties. This study aimed to determine the ultimate tensile strength (UTS) of AA6162 alloy with varying amounts of SiC (Silicon carbide) powder (3%, 6%, and 9% wt.) produced using the stir casting apparatus. The optimization of UTS was carried out using the Taguchi method, and Minitab statistical software was utilized to analyze S/N ratio and perform ANOVA (Analysis of variance) for the parameters: stir speed (SS), stir time (ST), and wt.% of reinforcements (RE). The ANOVA results revealed that stir time had the most significant impact on UTS, contributing approximately 42.3% to its improvement. The next substantial factor was the percentage of reinforcements, which contributed around 19.2%. Stir speed was identified as the least influential factor, accounting for approximately 18.5% of the variation in UTS. By considering these factors and optimizing stir time and reinforcement percentage, it is possible to enhance the UTS of AA6162 alloy particulate with SiC powder, leading to improved overall performance and mechanical properties.
