Fly Ash Particle Reinforced And Mechanical Properties Of AL6061 Graphite B4C Composites

D. Ramesh Kumar, B. SHANMUGASUNDARAM, P. Mohanraj


Fly ash particle reinforced with aluminium alloy composite materials used for various industrial applications like automobile, aerospace, aircrafts, substrate in electronics, turbine blades, brake pads, golf clubs and it is also used in home products. Metal matrix composites (MMCs) are increased mechanical properties like strength, yield strength, hardness, impact strength and to improve fracture toughness when compared to unreinforced alloys. The main aim is to fabrication of Al6061/Fly ash, Boron carbide, Graphite, and also Magnesium metal matrix composite by using stir casting process and also study the mechanical properties of the fabricated composite material. Fly ashes with aluminium, composite materials are good mechanical and physical properties for very high temperature, resistant to wear and lowest weight applications. Aluminium composite preparing from liquid phase reaction present a unique microstructure. The each phase is a continuous network penetrated by the network of the other constituent. It is an increased composites containing lowest cost expensive and lowest density reinforcements. The fly is very less expensive and very low density reinforced in solid waste by the product during combustion of coal in thermal power plants. Hence, fly ashes with aluminium composites reinforcement are to overcome the cost expensive for wide applications in automotive ancillaries, aircrafts, turbine blades and also engine applications. In future we add the graphite, boron carbide and magnesium with Al6061 & Fly ash to produce other metal matrix composites.
