Characterization of Microstructure and Mechanical Properties of Aluminum 2024 - Graphene - B4C MMCs Using Stir Casting

In the recent trends Metal Matrix Composites (MMCs) are increasingly becoming a new class of material in aerospace, automobile applications. Since their properties can be tailored through the addition of selected reinforcements, superior strength to weight ratio, wear and high temperature resistance. In the present study Aluminum 2024 alloy, Graphene and Boron Carbide (B4C) were taken as matrix and reinforcement respectively. The Microstructure and Mechanical properties investigation of Aluminum 2024, Graphene and Boron Carbide (B4C) composites containing the different weight percentages 0.25%, 0.5%, 0.75% and 1% of Graphene and 10% of boron by means of Stir Casting Technique. The structural properties of the prepared composite are observed using Scanning Electron Microscope. The Mechanical properties of the prepared composites like Tensile strength are determined by Universal testing machine, Hardness is determined by Brinell hardness test machine.
