▎ 摘  要

NOVELTY - A titanium base alloy graphene is prepared by mixing graphene and titanium and/or titanium alloy powder, adding organic solvent, subjecting to an ultrasonic wave oscillator, stirring to obtain mono-dispersed graphene solution, ball-milling, drying, subjecting dried powder to vacuum degassing, subjecting to hot isostatic pressing in the presence of an inert gas to obtain a cylindrical ingot, melting copper and/or copper alloy, adding prepared cylindrical ingot, mixing, casting to obtain alloy ingot, cooling to room temperature in the presence of inert gas, homogenizing, and extruding. USE - Method of preparing a titanium base alloy graphene. ADVANTAGE - The method is simple and low cost, has high production efficiency, and can be applied to large scale production. DETAILED DESCRIPTION - A titanium base alloy graphene is prepared by mixing 3-10 wt.% graphene and balance titanium and/or titanium alloy powder, adding an organic solvent, subjecting to an ultrasonic wave oscillator for greater than or equal to 2 hours, stirring to obtain mono-dispersed graphene solution, ball-milling at a speed of 300 revolutions per minute for 20-40 hours while controlling ball and material ratio of 10-15:1, drying at 50-60 degrees C, subjecting dried powder to vacuum degassing at 700-900 degrees C and vacuum pressure of 1x 10-3 Pa for 2-4 hours, subjecting to hot isostatic pressing at 700-900 degrees C and pressure of 100-200 MPa for 2-4 hours in the presence of an inert gas to obtain a cylindrical ingot having a diameter of 55-85 mm, melting copper and/or copper alloy at 30-80 degrees C in the presence of nitrogen and sulfur hexafluoride controlled at a ratio of 1:3.7, adding prepared cylindrical ingot, mixing, casting to obtain alloy ingot, cooling to room temperature in the presence of inert gas, homogenizing at 750-950 degrees C for 24-48 hours, and extruding at a pressure of 200-500 tons while controlling extrusion ratio at 15-20:1.
