Abstract
Reducing processing time and enhancing the performance of a product is the main focus of industries. Aluminum matrix composites (AMCs) find application in various engineering areas due to their low cost and tailorable mechanical properties. Many existing methods are available to fabricate AMCs, but stir casting is the accessible route. The existing stir casting methods employ a conventional heating source that consumes more time and energy. The application of microwaves in material processing has been explored because of its attributes, such as fast and uniform heating leading to a superior product. In the present work, aluminum matrix composite (AMC) was successfully developed using a novel microwave stir casting process. Aluminum alloy 6061 (AA6061) was used as a matrix and silicon carbide (SiC) particles (2 wt.%) as reinforcement. The prepared composite is characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Vicker’s microhardness test. The microstructural study confirms the dispersion of SiC particles in the AA6061 matrix without any voids. The microhardness study reveals the composite had a hardness of 62 Hv, increased by 12% compared with as-received AA6061.
