Bulk nanolaminated 0.4 wt% graphene (reduced graphene oxide, RGO)-reinforced Al–Mg–Si composite was fabricated using a modified powder metallurgy approach. The peakaged RGO-Al composite had significantly higher uniaxial yield (236.2 ± 10.8 MPa) and tensile strengths (320.3 ± 4.0 MPa), but shared sim...
