Abstract This study uses spark plasma sintering (SPS) to prepare graphene nanoplatelet (GNP)-reinforced titanium matrix composite materials. Heat treatment is used during rolling and annealing (RA this result represents an increase of 46% compared with pure titanium (PTi) under the same conditions. The reduction of area (ψ) of the 0.3 wt% GNP titanium matrix composite can reach 48%. The strengthening mechanisms include composite, grain and second-phase strengthening, wherein composite strengthening is the controlling factor. Additionally, the strength of composites at 1100 °C also increases, but ψ remains a lower level. The formation of nanocarbide particle layers causes a significant reduction in ψ.
