Abstract

The invention provides a preparation method of titanium matrix graphene alloy. The method comprises the following steps: preparing graphene and titanium and/or titanium alloy mixed powder, filling a jacket with the mixed powder, carrying out vacuum degassing, carrying out hot isostatic pressing, re-melting, and homogenizing. A certain amount of the titanium matrix graphene alloy precast ingots are re-melted in titanium alloy melt, the content of graphene in a composite material can be well controlled through calculating, and graphene cannot float, so the content of graphene in the titanium matrix graphene alloy can be accurately controlled; and the preparation method is provided on the basis of semi-continuous melting casting, and has the advantages of simple operation, high production efficiency, low preparation cost, and easy realization of large scale industrialization.

Description

technical field [0001] The invention relates to a preparation method of an alkene alloy, in particular to a preparation method of a titanium-based alkene alloy. Background technique [0002] Graphene is a new type of two-dimensional nanomaterial. Its nanosheet is a two-dimensional material with a single atomic layer thickness composed of sp2 hybridized carbon atoms. It is the thinnest and hardest nanomaterial known in the world, with a strength as high as 1.01Tpa. , is 100 times that of structural steel, but its density is 1 / 5 of that of structural steel. The thermal conductivity is as high as 5300W / m·K, which is higher than that of carbon nanotubes and diamonds. The electron mobility at room temperature exceeds 200,000cm2 / V·S, which is higher than that of carbon nanotubes or silicon crystals. The resistivity is only about 1Ω·m, which is higher than that of titanium or silver. Lower, the material with the smallest resistivity in the world. [0003] Graphene is a nano-scale...
