摘要

The effect of reinforcement with carbon nanomaterials on the mechanical properties of AZ31 alloy (Mg – 3Al – 1Zn) obtained by powder metallurgy methods was studied. Hybrid reinforcement GNP/CNT was used to obtain composites. The weight fraction of CNT (carbon nanotubes) in the base alloy AZ31 was kept constant at 0.25 wt.%. The weight fraction of GNP (graphene nanoparticles) was changed, % (wt.): 0.75; 1.25; 1.75; 2.25. The surface morphology of the alloy was analyzed using scanning electron microscopy. Microhardness and compressive strength of the composites were experimentally determined. The results showed that reinforcement increases the mechanical properties of the AZ31 alloy.
