▎ 摘　　要

NOVELTY - High-plastic quasi-mesh structure titanium-based composite material comprises titanium or titanium alloy, where titanium carbide phase and titanium carbide on graphene and titanium matrix are used as reinforcements. The reinforcement is uniformly and discontinuously distributed at the original beta-grain boundary of the titanium matrix to form a quasi-network structure, and the average diameter of the mesh in the quasi-network structure does not exceed 150 microns. The titanium-based composite material has a room temperature elongation of greater than 15%. USE - High-plastic quasi-mesh structure titanium-based composite material. ADVANTAGE - The high-plastic quasi-mesh structure titanium-based composite material increases the graphene and titanium matrix mixing evenness, overcomes the poor room temperature deformation capacity of graphite alkene titanium base composite material and disadvantage of poor extending plastic. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high-plastic quasi-mesh structure titanium-based composite material, which involves: (A) subjecting titanium or titanium alloy spherical powder particles to acid leaching treatment, followed by ultrasonic cleaning, and drying to obtain spherical or titanium alloy spherical powder particles; (B) ultrasonically dispersing the graphene nanosheet in a solvent to obtain a graphene nanosheet suspension solution; (C) mixing slurry preparation: adding the surface rough titanium or titanium alloy spherical powder particles obtained in the first step to the graphene nanosheet suspension solution obtained in the second step, stirring and homogenizing to obtain a paste-like mixed slurry; (D) mixing paste-like mixed slurry, placing in a star ball mill for ball milling treatment, and then drying and sieving to obtain a mixed powder; and (E) subjecting mixed powder to hot press sintering by a spark plasma sintering machine to obtain a high plastic quasi-mesh structure titanium-based composite material.
