Effect of reinforcement on Mechanical properties of Al6061 and B4C/ZrO2/SiC hybrid metal matrix composites

Abstract This research explains the Mechanical properties of Aluminium 6061 alloy and hybrid metal matrix B₄C/ZrO₂/SiC composites which is prepared by stir casting method. In this research B₄C has 2%composition, ZrO₂ was 2%,4% and 6% and SiC was 4%, 8% and 12% composition. The hybrid metal matrix composites are conducted hardness, impact, flexural strength, compressive strength, Tensile strength and Tensile fracture surface. These investigations study the effect of reinforcement on hardness, tensile, compression, impact and flexural strength. The effect of reinforcement study reveals that the pure Aluminium 6061 alloy shows poor results compared to Hybrid composites. The results confirmed that increasing in SiC percentage given high tensile strength, impact and hardness of the material. Adding SiC was given high quality mechanical properties. Adding 2% B₄C to Al6061 reduces the impact strength of the material. Reinforcement of ZrO₂ reveals improvement of mechanical properties. Additionally, this research studies the elongation, yield strength and behaviour between load and displacement of composite materials.
