Abstract

In this work, Mg-3 % Al alloy was reinforced by graphene nano-plates using powder metallurgy technique including microwave sintering and hot extrusion. Graphene nano-plates were synthesised using modified Hummer’s method. Raman test and FESEM analyses were carried out to confirm the formation of graphene nano-plates. The powders of Mg and 3 wt.% Al were mixed with graphene nano-plates. The microstructural characterization of the bulk composite revealed a reasonably uniform distribution of the graphene nano-plates in the matrix. The EDX result showed the presence of aluminium in the composite, while XRD result revealed that the aluminium powder completely dissolves and makes a solid solution of Mg and Al. An attempt is made to correlate the microstructural characteristics with the mechanical response of the monolithic and composite samples.
