Microstructural characteristics and mechanical behaviour of aluminium hybrid composites reinforced with groundnut shell ash and B 4 C

摘要: In this study, aluminium hybrid composites were fabricated by reinforcing eco-friendly agrowaste, groundnut shell ash and boron carbide using squeeze casting method. Groundnut added in ratios of 2.5:7.5, 5:5 7.5:2.5 percentages weight. The impact on mechanical properties namely density, hardness, tensile strength, strength was studied, the results compared with matrix alloy. fracture mechanism specimens studied scanning electron microscopy. Microstructural study reveals uniform distribution good bonding reinforcements clear interface composite. hardness increased up to a maximum 17% 18.32%, respectively, then slightly decreased while increasing particles. Increasing particles decreases density 12% 7.5%. Dimples, voids, cracks, clusters particle are characterised mechanism. Brittle fractures form formed due solid interfacial between Ductile reason for high dimples voids. has potential serve as reinforcement development composites.
