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. (C) 2014 The Korean Society of Industrial and Engineering Chemistry.
