Review of Aluminium (AA6061) Metal Matrix Composite (MMC) by Stir Casting Method

Abstract

Industrial development has boosted the use of aluminium to accommodate high demand. Among the most popular aluminium alloys is the AA6061 of the 6xxx series due to it characteristics. AA6061 is a preferred matrix material for Metal Matrix Composite (MMC) fabrication. This study comprehensively reviews an AA6061 aluminium matrix composite produced through the liquid processing technique-stir casting. This review focuses on process parameters, manufacture of conventional mixtures, range of reinforcement, mechanical and tribology properties of AA6061 composites. Significant findings show that increased reinforcement in AA6061 matrix composites greatly improves the properties, such as strength, hardness, ductility, and wear resistance. Producing AA6061 composites with various reinforcements such as organic, inorganic (carbide, oxides, borides and nitrides), hybrid, and other nanomaterials makes the composites more appropriate for high-stress applications. The AA6061 matrix has effectively included a broad spectrum of reinforcing materials, from micro to nanoscale, showcasing the adaptability and versatility of the stir casting method. Future studies should focus on improving AA6061 composite manufacture using advanced casting processes and comprehensive material characterization. These composites have great potential as advanced materials for several industrial applications due to its remarkable mechanical and tribological properties.
