Abstract Scope Aluminum Alloy 6061 and graphene metal matrix composites were produced using additive friction stir deposition (AFS-D), a solid-state additive manufacturing process. The graphene particles (GPs) were distributed into the aluminum matrix while simultaneously being additively deposited in the solid state in compositions between 0.25 and 2 wt.%. The depositions were characterized with X-ray diffraction, optical and electron microscopy, and Raman spectroscopy techniques. The GPs were distributed within grains and the GPs reduced in size from several microns to less than 0.2 µm wide through this solid-state process. Differences in particle dispersion between the retreating and advancing sides of tool rotation were quantified in the deposition. Raman spectroscopy confirmed the graphitic nature of the GPs in the matrix after deposition, which showed an increase their disorder. The dependence of the resulting hardness of the deposit on the graphene content, dispersion degree, and location was quantified using Vickers microhardness measurements.
