| Abstract | ||||
| This study investigation the effect of silicon carbide (SiC) content and hot compaction temperature on the microstructural, mechanical, tribological, and physical properties of Al/SiC nanocomposites. Composites were synthesized via high-energy ball milling followed by hot compaction, with SiC varied at 2.5, 5, 7.5, and 10 wt.% and compaction temperatures set at 500 °C, 550 °C, and 600 °C. SEM analysis confirmed uniform dispersion of SiC particles within the aluminium matrix, particularly in the Al/5 wt.% SiC composite. The highest relative density was achieved by the Al/5 wt.% SiC sample compacted at 600 °C. This composition also demonstrated the most notable enhancements in performance, with improvements of 135% in wear resistance, 87% in compressive strength, and 82% in hardness compared to unreinforced aluminium. These results suggest that a 5 wt.% SiC reinforcement and 600 °C compaction temperature offer an optimal balance of properties for structural applications, highlighting the significance of processing parameters in tailoring composite behaviour. | ||||
