摘要

The microstructure, physical properties (density, porosity) and mechanical properties (compressive strength, microhardness) of composites with a matrix from magnesium alloy AZ31 (Mg – 3 wt.% Al – 1 wt.% Zn) reinforced with various amounts of graphene nanoparticles (GNPs) obtained by powder metallurgy is investigated. The GNPs content in the composite is 0, 0.75, 1.25, 1.75 and 2.25 wt.%. It is shown that the density before and after the sintering, the microhardness and the compressive strength of the composites increase with the increase of the content of graphene nanoparticles in the structure to 1.75 wt.%.
