- Abstract
The mechanical and structural properties of aluminum matrix nanocomposites (AMNCs), such as hardness, toughness, and damping ratio, are critical for a wide range of engineering applications. In this study, Al 6061 was selected as the matrix material, with silicon carbide (SiC) and aluminum oxide (Al2O3) nanoparticles utilized as reinforcements. The AMNCs were fabricated through the stir casting method, with various weight ratios of nanoparticle reinforcement. The damping behavior, hardness, and toughness of the composites were evaluated at different reinforcement levels. It was found that the damping ratio of the AMNCs increased significantly relative to the base Al 6061, with the optimum enhancement observed at approximately 2% reinforcement. At this nanoparticle concentration, both the impact resistance and hardness were notably improved. The findings demonstrate that the incorporation of SiC and Al2O3 nanoparticles into Al 6061 leads to substantial improvements in the mechanical and structural properties of the composite, thus highlighting the potential of AMNCs for advanced applications requiring superior performance in terms of energy dissipation, strength, and durability.
