Development of Hybrid Aluminium Alloy Composite

Abstract

Aluminium is a kind of metal which has variety of uses in advancing modern technology. MMC’s are made by introducing a reinforcing material in the metal matrix. The reinforcement material here used is SiC and BC and Al-6061 is the matrix. Aluminium, SiC , Boron Carbide MMC are prepared by powder metallurgy and casting. According to most various literature it is understood that the SiC is used as major reinforcement material. In present investigation an MMC with Al-6061 as base matrix and SiC particulate reinforcement. It is also added 2% boron carbide to understand the influence on material properties.

 In current study the sample of MMC with Al6061 as matrix and 2% Boron Carbide as reinforcements we have added varied fraction of SiC i.e.; 0%,4%,6%,8% by weight prepared by stir casting method. The samples are prepared as per ASTM standard to investigate the influence of reinforcement particle on mechanical properties such as tensile strength, impact strength, wear resistance, Brinell hardness. The properties are compared to understand the influence. Achieving homogeneity is the major challenge and it affects the properties of the composite directly. The Al alloy composite material has high strength, high stiffness, good thermal stability, good corrosion and wear resistance and good fatigue life. Aluminum is most attractive base metal for MMC due to its light weight. There are variety of applications for Al based MMC’s in modern technological space.
