Abstract : The current research work includes analysis of the impact of reinforcements B4C /SiC, on the mechanical Properties of Al-6.6Si-0.4Mg alloy. The reinforcement content was varied between 5- wt% and 10- wt% respectively. The mechanical properties- percentage elongation, hardness, tensile and yield strength were observed for varying weight percentage of reinforcement content and compared. The micrographs of the cast specimens were distinguished under an optical microscope and a scanning electron microscope and it was noticed that as the weight percentage of the added reinforcement content increased there was a subsequent transition from learner to finer distribution. Mechanical properties – hardness, tensile and yield strength displayed a similar trend of improvement in corresponding properties with a subsequent increase in the reinforcement wt-%. However, in the case of percentage elongation, there was a decrease in property with a corresponding increase in reinforcement.
