“…Vapor deposition, thermal spraying, centrifugal casting, slip casting, tape casting, gel casting, laser deposition, sedimentation, electrochemical methods, and powder metallurgy (P/M) are the production techniques commonly used for FGMs [5,6]. P/M over other techniques, it has some advantages such as availability of good raw material, suitable for mass production, control of chemical composition, production of porous and complex shapes and metal matrix composites, which are very difficult to produce by casting method due to density difference [7]. In the last few years, among metal-based materials, Al, due to their good thermal and electrical conductivity, high tensile strength-to-weight ratio, high hardness, and ductility properties; is of great interest in structural and functional applications [8,9].…”
