A method of reinforcing a metallic material, comprising: adding graphene to an alcohol solution; subjecting the alcohol solution containing graphene to sonication; mixing an aluminum powder with the alcohol solution containing graphene; milling the aluminum powder and alcohol solution containing graphene mixture; drying the aluminum powder and alcohol solution containing graphene mixture to form a composite powder, wherein the composite powder comprises from 0.5 to 2.0 wt. % of the graphene; subjecting the composite powder to a densification process followed by a hot isostatic pressing treatment to form a composite material, wherein the densification process comprises loading the composite powder into a sheath and oscillating to increase an apparent density to a density that is not lower than 1.6 g/cm 3; and molding the composite material by hot extrusion. Currently amended
The method of claim 1, wherein the alcohol solution containing graphene is sonicated for about 30 minutes. Original
The method of claim 1, wherein a ratio of mass of aluminum powder added to a volume of the alcohol containing graphene solution is about 10:1 to 0.5:1. Previously presented
The method of claim 1, wherein the densification process further comprises: vacuumizing the composite powder in the sheath; and sealing the sheath by welding with the composite powder inside when the pressure reaches 1.Ox 10- 3 Pa. Previously presented
The method of claim 1, wherein the hot isostatic pressing treatment is performed at 480 ° C and 110 MPa for two hours. Original
The method of claim 1, wherein the molding by hot extrusion occurs at a temperature of 440 ° C to 480 °C. Original
Embodiments described in the patent, grouped by the materials and process steps they use.
