Optimization on Stir Casting Process Parameters of Al7050/Nano-B4C Metal Matrix Composites

Aluminum matrix composites are widely employed in aerospace, military, automobile, and transport applications. The high-strength with low-weight materials required to fulfill the requirement of high-performance reinforced hard reinforcements obtain high-strength-to-weight properties for using process parameters fabrication technique define mechanical tribological properties. Many types optimization tools used optimizing method. In this research, aluminum alloy 7050 boron carbide selected as material reinforcement material. Al7050/B4C is produced by stir casting on done Taguchi approach. L9 orthogonal array chosen investigation. input wt% B4C, stirring time (10, 15, 20 min), speed (300, 350, 400 rpm), melting temperature (700, 750, 800°C). microhardness a valuable response parameter parameters. influencing sequence determined mean table. speed, time, temperature. 9 addition increases microhardness, it higher than other wt%. optimum combination carbide, 750°C temperature, 350 rpm 15 min (A3B2C2D2). percentage value improvement 20.3%.
