摘要：

Metal matrix composites are light and robust materials that are widely used in a variety of industrial applications. In this study, Graphene Nanoparticles (GNP) were subsequently reinforced with Al6061 Aluminium (Al) alloy at various weight percentage ratios (0, 0.1, 0.3, 0.4), and Nanocomposites were created using the stir-casting process. Scanning electron microscopy was used to characterise the structures, and tensile and hardness tests were performed to assess the composites' mechanical characteristics. The microstructural data demonstrate that nano-composites are distributed randomly. This research found that adding graphene nanoparticles to materials increased yield strength, ultimate tensile strength, as well as hardness. The as-cast tensile strength and compressive strength of the GNP/Al6061 Nanocomposites were increased by 37% and 34%, respectively, when compared to the unreinforced Al6061 alloy. The results show that Sample 2 (Al 6061 per cent + GNP 1 per cent) has better hardness properties than the other two samples because the reinforcement materials have been increased. Through these experiments, the mechanical properties of a composite material were made better than they were with the GNP. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
