The current study explores the feasibility of artificial aging treatment to aluminium alloy 6061 hybrid composites reinforced with graphite and fine granite particulates to suit structural applications. Aging at 100 °C retrieved a better response of the hybrid composites as compared to that at 150 °C in terms of peak hardness and strength. Among the five different stir-cast compositions, the composition of aluminium 6061 with 2 wt. % graphite and 4 wt. % granite showed enhanced mechanical properties than that of the base alloy as well as mono reinforcement type composites which was attribued to the formation of rod-shaped β-Mg2Si precipitates.
