Abstract
The aluminum alloys exhibit interesting combination of properties such as light weight, ductility, and corrosion resistance, as well as high electrical and thermal conductivity. Thus, they have been widely used in the automotive, aeronautical, aerospace and military applications such as in the fabrication of frame and body parts of commercial and military aircraft and vehicles, in which effective formability and high specific resistance are needed. Nevertheless, the aluminum alloys have low hardness, resulting in poor wear resistance. Wear being one of the most common phenomena in engineering practices, the friction and abrasion mechanisms reduce the lifetime of aircraft and vehicles parts exposed to different mechanical actions [1]. Therefore, the academic and scientific research in materials science plays a vital role in ensuring the development of engineering materials with improved mechanical performance. In this regard, the A356 aluminum alloy is one of the most widely used lightweight materials in the aircraft and automotive components due to its good castability, relative high mechanical strength and responsive to heat treatments. The mechanical properties of A356 alloy depend on different factors such as chemical composition, microstructure and heat treatments. The mechanical performance of this aluminum alloy can be enhanced by the fabrication of metal
