ABSTRACT
Graphene and its derivatives are excellent reinforcements for the metals. The tailoring of properties of metal matrix nanocomposites (MMNCs) resulted in wide use of graphene reinforced MMNCs (GMMNCs) in various applications like aerospace, automobile, electronics etc. The processes, properties, microstructure, strengthening mechanisms, and applications are discussed throughout the chapter. The chapter is focused on graphene, and its derivate reinforced metal matrix nanocomposites. The physical and chemical synthesis processes were discussed at the starting of the chapter. Aluminum, magnesium, copper, nickel, and titanium-reinforced with graphene and its derivatives were mainly discussed in the chapter. The mechanical properties of these nanocomposites focusing on the yield strength, ultimate strength, modulus, hardness, and elongation are discussed in detail. The microstructure studies using scanning electron microscopy (SEM) and X-ray diffraction (XRD) are also presented. The popular strengthening mechanisms to evaluate the strength of the nanocomposites are also discussed. Toward the end, the applications, challenges faced, and future scope are presented in brief.
