Mechanical Characterization and Machinability Optimization of Stir-Cast Al6061–SiC Metal Matrix CompositesBy B. Suresh Kumar Reddy, B. Subba Rao, PVR Girish Kumar, S. Gajanana, B. Ravi Kumar
Abstract: This study presents the fabrication, mechanical characterization, metallurgical analysis, and machinability optimization of Aluminum 6061 reinforced with Silicon Carbide (SiC) metal matrix composites (MMCs) at three weight fractions: 5%, 7.5%, and 10%. Composites were manufactured using the stir casting technique, followed by comprehensive mechanical testing (tensile, hardness, and impact), optical microscopy, and scanning electron microscopy (SEM). Machinability was assessed through turning experiments on a lathe using an L9 Taguchi orthogonal …
