摘要：The Aluminium alloy composite are made by mixing particulate in a molten alloy. These composites arehard, rigid, and tough and possess good mechanical properties their ductility will decrease and will gain betterresistance to corrosion these type of aluminium metal matrix composites are used in automotive application, aerospaceand construction. They even are enriched with good weight to strength characteristics. The present work is concentratedin a view to produce such type of enhanced composites. the cheaper method of fabricating Aluminium metal matrixcomposite is by stir casting method and by proper reinforcement selection. Silicon Carbide (SiC) is ceramic materialwhich is hard and can enhance aluminium strength, fly ash is a power plant debri and easily available¹. Thecomposition is selected on weight percentage basis SiC with 6 % and 9% and fly ash with constant 15 % and AL6061T6 alloy as matrix material. With proper vortex formation particulate dispenses wisely which is evident from SEM andEDS analysis. The mechanical tests are carried out and it is observed that tensile and hardness improved comparedwith monolithic alloy. The fatigue test was conducted using fully reversed cycle R=-1 using rotating bending machineat room temperature. Loads are defined by considering 0.5UTS, 0.7UTS and 0.9UTS to plot S-N curve.
