The Mg-Al-graphene nanoplatelets (GNPs) nano-composites were synthesized using the powder metallurgy method. The effect of Al?GNPs hybrids addition in to pure Mg was examined through tensile and Vicker hardness tests. The GNPs content was kept constant (0.18 wt.%) and Al content was varied from 0.5 wt.% to 1.5 wt.%. The increase in Al content led to increase in 0.2%YS, UTS and failure strain (%). However for Al content exceeding over 1 wt.%, the failure strain(%) started to decrease. The best improvement was achieved with 1 wt.% Al (Mg-1.0Al-0.18GNPs). Mechanical strength of synthesized composites proved to be better than Mg-Al-CNTs and Mg-ceramic composites.
