Potentiality of artificially aged aluminium 6061 hybrid composites reinforced with granite and graphite micro–fillers for structural applications: Potenzial von künstlich gealterten, mit Granit und Graphit verstärkten Aluminium- (6061) Hybrid-Verbundwerkstoffen für konstruktive Anwendungen

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.
