Abstract: The present work is focused on the study of behavior of Aluminium Alloy (A356) with Aluminium Nitride (AIN) and Magnesium (Mg) composite produced by the stir casting technique. Different % age of 3, 6 & 9 AlN and 0.5 & 1 Mg of reinforcement are used. Tensile Test, Micro Hardness Test, Impact Test are performed on the samples obtained by the stir casting process. Microstructure analysis has done to know the presence of the structure of reinforced material. Hardness tester is employed to evaluate the interfacial bonding between the particles and the matrix by indenting the hardness with the constant load and constant time. Microscopy was done to know the distribution of AlN/Mg particles in Aluminium alloy. It has been observed that with the addition of reinforcements 3, 6 & 9 % AlN and 0.5 & 1 % Mg in base metal A356, ultimate tensile strength, impact strength and hardness were found maximum corresponding to 9% aluminium nitride (AIN) and 1% Magnesium (Mg).
