This research, the focus was on developing a modified microstructure in the Al-7068/Al₂O₃ (Aluminum oxide) combination using powder metallurgy techniques. The goal was to vary the sizes of reinforcement particles within the substrate to investigate their effects taking place this total nano-composite mechanical property. Specifically, nanocomposites among 9 vol.% alumina 40 nm were fabricated in an aluminum matrix, and a separate set of micro-composites with a similar composition (average size of 20 μm) was created for comparison. The characterization of these composites involved X ray diffraction (XRD) and scanning electron microscopy (SEM), along with tests for density, microhardness, strength that squeeze, resilience wearable, along with deterioration confrontation. This result showed that the alumina nanoparticles exhibited strong physical bonding with the aluminum matrix, leading to reduced aggregation and no new phases being formed during the powder metallurgy process, even at relatively low operating temperatures.
