Abstract
The invention discloses a titanium-copper alloy explosion-proof material and a preparation method thereof. The material comprises the following components of, in percentage by weight, 30%-40% of titanium-copper alloy, and 60%-70% of graphene; and the titanium-copper alloy comprises the following components of, in percentage by atomic weight, 60%-65% of titanium, 30% of copper, and 5%-10% of nickel. The preparation method comprises the following steps of 1) taking high-purity titanium, copper and nickel as raw material, carrying out high-temperature smelting in an argon atmosphere, grinding toremove oxide skin, and grinding into powder to obtain alloy powder; 2) preparing natural graphite or artificial graphite into powdery graphene; and 3) mixing part of the alloy powder with powdery graphene, loading the mixture into a mold, and sintering to obtain a preform; and placing the preform into a crucible, vacuumizing, heating the remaining alloy powder to be molten, introducing the alloy melt to permeate the preform, and cooling to room temperature. The titanium-copper alloy and the graphene are prepared into the explosion-proof material in the modes of combined mixed sintering, alloymelt infiltration and the like, the overall strength of the material can be improved, and the explosion-proof material has excellent explosion-proof performance.
Description
technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a titanium-copper alloy explosion-proof material and a preparation method thereof. Background technique [0002] In recent years, due to their high specific strength and excellent corrosion resistance, titanium and titanium alloys have been applied in chemical industry, metallurgy, biomedicine and other fields. Among them, titanium-copper alloy has high strength, high elasticity, excellent heat resistance, fatigue resistance and good bending performance, and is widely used in light industry and construction industry. In addition, titanium-copper alloys have great application potential as medical implant materials. Graphene is a two-dimensional carbon nanomaterial in which carbon atoms form a hexagonal honeycomb lattice with sp² hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in mater...
