Gr/Ni
Aluminum (Al) composites have been applied in the automotive and aerospace industry [1] due their low density and high strength. These materials can be produced with oxides, carbides or nitrides dispersed in the metallic matrix by mechanical milling. Recent studies show an increment in mechanical properties with different reinforcing materials as nanotubes [2-4], graphenes [5] and carbon [6]. These additives induce different reinforcement levels, depending how do they interact with material dislocations [7]. Graphite (Gr), an allotropic form of carbon, is used as reinforcing additive because it is cheap, abundant and can be easily comminuted. D. Yadav et al. [8] added nickel (Ni) particles to an Al matrix by friction stir processing, finding that Ni helps to obtain grain refinement and increase the mechanical properties of the prepared composites.
