Development and Mechanical Characterisation of Al6061-Al2O3-Graphene Hybrid Metal Matrix Composites

MMC based on aluminium (Al) were produced for light-weight applications especially in aviation and automobile areas. Present paper deals with the fabrication mechanical performance of AA6061 matrix composites fortified Al2O3 (alumina) graphene particulates. Fluid metallurgy method namely stir casting route was employed fabricating hybrid composites. Al2O3p powder are mixed different weight fractions which (1 wt. %) particle reinforcement is held consistent differed freely 5, 10 15 %. Using optical analyser SEM equipment, microstructural examination carried out result reveals that particles prevalently homogeneously appropriated grain limits Al disseminated between as-cast MMC’s. Detailed analysis investigation microstructure aspects Al6061-graphene-Al2O3p presented by following ASTM guidelines; results uncovered increment particles, there an enhancement hardness, ultimate strength, yield strength a decline elongation values however noticed when contrasted Al6061 alloy. Fractography revealed dimples unreinforced alloy composite.
