Nowadays, demands for developing metal matrix composites for use in high performance applications, have been significantly increased. Among these composites, aluminum alloy matrix composites attract much attention due to their lightness, high thermal conductivity, moderate casting temperature, etc. Various kinds of ceramic materials, e.g. SiC, Al2O3, MgO and B4C, are extensively used to reinforce aluminum alloy matrices. In this project Aluminium Alloy (LM4) is reinforced with 1, 1.5, 2.5 and 5% of nano particle of Aluminium oxide (Al2O3) and fabricated by using stir casting method. The fabricated Aluminium oxide (Al-Al2O3) nanocomposite materials are tested using tensile and hardness testing machines to determine its Mechanical properties. And the results are compared for choosing the best composite .A microstructure test was also conducted to determine the best results. Finally the composites are analyzed using Ansys version 10.0 Software.
