“…1% reinforcement of nano particles improved vickers hardness by 21%, 2% and 3% reinforcement showed increments of 26% and 28%, respectively. Abeens et al [35] studied the wear and mechanical behaviour of an aluminium 8081-based composite reinforced by microsized TiO 2 and nanographene. The aluminium matrix sample containing 10% TiO 2 and 2% Gr has a high hardness value of 103.3 BHN.…”

Due to their effectiveness, lightweight materials have gained international attention in recent decades, with industrial sectors being the primary users of them. Metal matrix composites with nanohybrid reinforcement are a unique composite system combination that enhances the material’s mechanical qualities. In the present article, the mechanical properties of graphene nanoplatelets (GNP) and titanium dioxide (TiO2)-reinforced aluminium 7075 alloy are discussed with varying weight percentages of reinforcements prepared by the stir casting technique. 1 wt.% GNP with and 3 wt.% TiO2-reinforced composites show optimum properties within the range of reinforcement studied, with a 71.9% increment in tensile strength and an 86.6% improvement in microhardness observed; however, elongation is decreased by 31.7% in contrast to the base alloy. Maximum toughness is found to be in 0.5 wt.% GNP with 1 wt.% TiO2-reinforced nanohybrid composites. XRD results show phase analysis. SEM analysis of the fractured surface reveals a mixture of ductile and brittle fractures.
