In most of the engineering applications like aerospace, marine, defence and military applications, metal matrix composite has a major role due to its enhanced mechanical and material properties such as high strength, high stiffness, and light weight, wear resistance etc. Most of the components, which are being used in aerospace, military, defence, automobiles and marine applications are subjected to high impact load, fatigue, creep, wear, corrosion, vibration and high thermal stresses. Hence there is a need of development of metal matrix composite with higher strength, wear resistance and hardness. AA7075 reinforced with various wt% of Si3N4, TaC & Ti nano ceramic reinforcement particulates were prepared by liquid route stir casting technique. The experimental study reveals that tensile strength & compression strength increases due to increase in wt% of nano reinforcements. Also, it was revealed that above 0.5 wt% TaC, 0.25 wt% Si3N4, the ductility of the developed AMCs gradually decreases due to the addition of more wt% of hard reinforcement in to the matrix material. The addition of Si3N4, Ti and TaC particles improved the strength, microhardness and wear resistance of the developed AMCs.
