Influence of Agricultural Waste and Ceramic Reinforcement on the Hardness of Aluminium 7075 Hybrid Composites
No full textMetal Matrix Composites offer superior mechanical properties compared to monolithic alloys, making them highly suitable for demanding engineering applications. This study investigates the mechanical behavior of an Aluminum 7075 alloy reinforced with Tungsten Carbide (WC) and Cow Dung Ash (CDA) fabricated via stir casting. The primary objective of this study was to evaluate the effect of hybrid reinforcement on the composite\u27s hardness. The results indicated that the incorporation of WC and CDA significantly enhanced the hardness of the Al 7075 matrix. Specifically, the hybrid composite containing 3.5 wt.% WC and 1.5 wt.% CDA exhibited the highest hardness (35 HRB), representing a substantial improvement compared to the lower-WC compositions studied. These findings suggest that modifying Al 7075 with WC and CDA is a viable strategy for developing cost-effective high-strength composites
