Study on aluminium metal matrix composites reinforced with SiC and granite powder

Abstract

The exceptional physical and mechanical properties of Aluminium matrix composites (AMCs) have garnered considerable attention, rendering them highly promising materials for a wide range of applications. The integration of reinforcements into the metallic matrix results in enhanced stiffness, specific strength, wear resistance, creep resistance, and fatigue resistance in AMCs as compared to conventional engineering materials. The present study is centred on the examination of the mechanical characteristics of Aluminium Matrix Composites (AMCs) that have been fortified with Silicon Carbide (SiC), Granite and Graphite powder. Composites featuring varying concentrations of SiC, Granite and powder were produced via a stir casting process. The composites were assessed through the implementation of ASTM standard procedures for conducting hardness, tensile, and shear strength tests. The findings underscore the potential of said composites for diverse applications that necessitate elevated levels of durability and resistance to abrasion.
