The current investigation involved the fabrication of Al6061/SiC/B4C composites with different sintering temperatures using the vacuum casting technique. The morphology and mechanical properties of these composites were then analyzed and are summarized. Morphology studies show that increasing the sintering temperature leads to notable grain refinement, even distribution of reinforcement, and minimal porosity. The incorporation of SiC and boron carbide particles into the matrix enhanced the hardness of 18.37% of the composites by serving as a hindrance to the movement of the matrix lattice dislocations. An increase in sintering temperature results in greater plastic deformation of composites, hence cracks formed and propagated easily due to their brittle nature ultimately reducing the impact strength of composites. The robust adhesion between the Al6061 matrix and the SIC and boron carbide particulates in particle-reinforced composites efficiently inhibited delamination and decreased the rate of wear composites.
