Abstract
Generally aluminiums are used for various applications in industrial sectors and home based products. Metal matrix composites (MMCs) possess significantly improved properties including high specific strength, specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. The objective of the project is to fabricate Al356/Fly ash, Graphite& Boron Carbide metal matrix composite by using stir process and study the properties of the fabricated composite. Co-continuous alumina/aluminium composite materials with excellent physical and mechanical properties offer great potentials for lightweight, wear resistant, and high-temperature applications. Composite materials prepared from a liquid-phase displacement reaction present a unique microstructure in which each phase is a continuous network penetrated by the network of the other constituent. There has been an increasing interest in composites containing low density and low cost reinforcements. Among various discontinuous dispersions used, fly ash is one of the most inexpensive and low density reinforcement available in large quantities as solid waste by-product during combustion of coal in thermal power plants. Hence, composites with fly ash as reinforcement are likely to overcome the cost barrier for wide spread applications in automotive and small engine applications.
