“…Nano materials like Graphene, nano-diamonds and carbon nanotubes exhibit outstanding mechanical, tribological, electrochemical and thermal properties owing to their efficient structures. Graphene has begun as a key class of advanced and unique reinforcement material in aluminum alloys due to its high strength, large aspect ratio, improved thermal properties and high elastic modulus [19]. However, a little research work has been revealed with Beryllium aluminum silicate and Graphene as reinforcements in Al-MMC.…”

The emerging technologies and trends of the present generation require downsizing the unwieldy structures to lightweight structures. Aluminum matrix composites are tailored candidate materials for aerospace applications due to their outstanding greater strength to weight ratio and low wear rate. In this study, Al7075 alloy-Beryl-Graphene hybrid composites are developed by using stir casting process. Graphene weight percentage was varied from 0 wt. % to 2 wt. % in steps of 0.5 wt. %. Whereas for Beryl 6 wt. % is used thorough out the study. The casted specimens were heat-treated at T6 solutionizing temperature of 530±5oC for 8 hours. After the heat treatment the specimen are quenched in boiling Water and Ice. The microstructure of the newly developed hybrid MMCs has been investigated by TEM and SEM. The microstructural study reveals the uniform distribution of reinforcement into matrix materials. The hardness and wear behavior of matrix and hybrid composites before and after heat treatment examined by Brinell hardness test and Pin-on-disc test machine respectively. The heat-treated Al7075-Beryl-Graphene hybrid composites significantly improved the hardness and low wear rate compared to base matrix Al7075 alloy
