Abstract

The invention belongs to the technical field of high polymer materials, aiming to solve the problems that conventional equipment for preparing Ti2AlC material is expensive and has the disadvantages ofhigh cost, complex process and difficulty in industrial promotion, and products obtained by the equipment always contain impurity phases which cause poor performance to limit application of the material. According to the preparation method, Ti powder, Al power and carbon nano tubes are taken as the raw materials to prepare the compact TiAlC material at one step by a near-isothermal canned forgingmethod; the powder mixing process is simplified. Since the operation is carried on a common hydraulic press directly, industrial production is facilitated, processing is simplified and cost is lowered. Further, by the way of high-temperature large-deformation, the Ti2AlC material prepared by the method has the advantages of high compactness and high fineness of grains.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of dense Ti2AlC material. Background technique

[0002] The new ternary layered ceramic material Ti2AlC has become a research hotspot of many materials scholars at home and abroad in recent years because of its excellent properties. It has both metal properties, good thermal and electrical conductivity, low Vikers hardness, can be machined like metal, and has ceramic properties, high melting point, high thermal stability and good oxidation resistance. At the same time, it also has peculiar properties such as self-lubrication and thermal shock resistance. As an intermetallic compound material, it has the properties of both metal materials and ceramic materials. It has machinability and excellent high-temperature oxidation resistance. These excellent properties make It has broad application prospects, especially in the fields of high-temp...
