Abstract

Abstract: The current study is meant for LM-12 aluminium alloy reinforced with different weight percentage of SiO2 and carbon nano tubes hybrid metal matrix composite development using stir casting method with sand mould technique. Further, heat treatment was carried out using ice quenching process for evaluating tests such as Microstructure analysis, Tensile strength and Hardness of Hybrid Metal Matrix Composite which were developed experimentally. Tests were performed on different specimens within the heat treated casting, according to ASTM standards. The microstructures of the composites were concentrated to know the scattering of the reinforcement particulates in Matrix. It has been observed that expansion of particulates essentially enhances tensile strength and hardness..
