The Aluminium alloy composite are made by mixing particulate in a molten alloy. These composites are hard, rigid, and tough and possess good mechanical properties their ductility will decrease and will gain better resistance to corrosion these type of aluminium metal matrix composites are used in automotive application, aerospace and construction. They even are enriched with good weight to strength characteristics. The present work is concentrated in a view to produce such type of enhanced composites. the cheaper method of fabricating Aluminium metal matrix composite is by stir casting method and by proper reinforcement selection. Silicon Carbide (SiC) is ceramic material which is hard and can enhance aluminium strength, fly ash is a power plant debri and easily available¹. The composition is selected on weight percentage basis SiC with 6 % and 9% and fly ash with constant 15 % and AL6061 T6 alloy as matrix material. With proper vortex formation particulate dispenses wisely which is evident from SEM and EDS analysis. The mechanical tests are carried out and it is observed that tensile and hardness improved compared with monolithic alloy. The fatigue test was conducted using fully reversed cycle R=-1 using rotating bending machine at room temperature. Loads are defined by considering 0.5UTS, 0.7UTS and 0.9UTS to plot S-N curve.
