In this work, 2 wt.% Silicon Carbide (SiC) particulate reinforced aluminium 1100 (AA1100) Metal Matrix Composite (MMC) was fabricated through Friction Stir Processing (FSP). The average particle size of the SiC used in the present study was analysed using particle size analyser which was found to be 12 µm. The microstructural analysis of base metal and processed samples were carried out with Scanning Electron Microscopy (SEM). Vickers hardness test was carried out at 500 g load with 10 s dwell time. The hardness value of the composite was 52% higher than the base metal. In addition to that, the composite layer has been identified from the hardness test carried out along the depth from top to bottom of the processed plate. The tensile test was performed on MMC which revealed that Ultimate Tensile Strength (UTS) of MMC was 97% higher than the base metal with an increase in stiffness and reduction in strain to failure values. The tribological performance test was carried out with pin on disc tribometer. The wear rate of both the base metal and composite were calculated and it was noted that the wear rate of MMC has decreased by 57% when compared to the base metal. Reduction in wear rate of MMC was attributed to the SiC addition on AA1100 through FSP. Coefficient of Friction vs Time plot indicated lesser frictional force on the MMC surface which implies that SiC in the aluminium matrix acted as a solid lubricant during wear test. Thus, the fabricated AA1100-SiC MMC have high hardness and UTS value with a slight reduction in ductility.
