Aluminum-7075 series alloys commonly used in transportation applications are aerospace, aviation, marine and automobile due to their good mechanical properties and low density and high strength-to-density ratio [1]. The present review focuses on mechanical properties, tribological properties and corrosion behavior of Al-7075 metal matrix composites (AMMCs) by the addition of desirable reinforcements. The objective is to review the literature on fabrication of the aluminum metal matrix composite materials by combining alloys and reinforcements. The reinforcements may be particulate SiC, Al2O3, Gr, TiO2, bagasse ash, etc. These particulate reinforcements are incorporated in the stir casting method. The results revealed that, there is significant improvement in mechanical properties. Superior wear and corrosion resistance, low coefficient of thermal expansion as compared to conventional base alloys. (C) 2019 The Authors. Published by Elsevier B.V.
