- Abstract
Aluminum based metal matrix composites reinforced with Silicon carbide particulate have gained wide acceptance in several engineering applications. Friction Stir Processing (FSP), a novel solid state processing technique, has gained acceptance as a potential method for fabricating composites with enhanced surface properties. This paper demonstrates the fabrication of AA6061-SiCP Composites using FSP for achieving higher ultimate tensile strength and microhardness. The experiments were conducted based on three FSP parameters, namely tool rotational speed, traverse feed and tool tilt angle. The optimal process parameters were identified by using desirability function analysis. Experimental results confirmed that the composites fabricated, have higher ultimate tensile strength of 178 MPa and microhardness of 156 Hv. The effect of process parameters on the responses was analyzed. The results of microstructural analysis show that the defect free composite region and uniform particle distribution are obtained using optimized parameters.
