Abstract
Composite materials play an important role in automotive, aerospace, marine, transportation and defence applications because of its high strength to weight ratio, high stiffness to weight ratio, superior mechanical properties with wear resistance. Aluminium alloys have been used because of its light weight and better corrosion resistance. In this present work an attempt has been made to prepare the composites. LM6 aluminium alloy reinforced with boron carbide (B4C) and fly ash particles compositeshave been prepared using stir casting process. Microstructure, hardness, tensile strength, ductility and dry sliding wear behaviour of composites have been investigated. The results reveal that hardness of composites increased with increasing wt% of reinforcements. Maximum hardness of 124 BHN was observed for the composites had 5wt% of fly ash and 10 wt% of boron carbide particles. This composite can be used in various applications because of its better hardness compared to LM6 aluminium alloy.
