Abstract |
|
Metal matrix composites (MMCs) constitute an important class of design and weight efficient structural materials that are encouraging every sphere of engineering applications. Since, there has been an increasing interest in composites containing low density and low cost reinforcements. In the present work, Friction Stir Welding (FSW) has been used to join the AA6061 reinforced with SiC and Rice Husk-Ash metal matrix composites (MMCs). Accordingly, rectangular composite plates were fabricated through stir casting route, then these plates were welded by using FSW. By Taguchi method using L9 orthogonal array, the optimum of process parameters has been determined. ANOVA analysis has been carried out to determine the percentage contribution of each factor on Tensile Strength and Hardness. Micro-structural characterization of the stir zone was carried out through Optical Microscopy (OM). The uniform grain distribution has been observed across the stir zone of AA6061/SiC/Fly-Ash composites after FSW. |
