Problems solved by technology

As reported in the literature (Scripta Materialia 53 (2005) 1369-1372), the use of simple V elements for solid solution modification research has greatly improved its mechanical properties. The same method can use Zr elements for solid solution modification research, but The raw material cost of this method is higher, and the synthetic temperature is higher at the same time, is unfavorable for its industrial production; 2 o 3 Particles can pair with Ti 2 AlC has a similar structure to Ti 3 AlC 2 Modification of material properties
However, the methods currently used are relatively simple, and at the same time, the preparation method is mainly based on Al 2 o 3 a

Abstract

The invention discloses a (Ti, Zr)2AlC/Al2O3 solid solution composite material and a preparation method thereof. The method comprises the following steps of: performing a hot-press sintering process on 39.38 to 70.08 weight percent of Ti powder, 20.11 to 22.85 weight percent of Al powder, 6.37 to 8.84 weight percent of C powder and 0.97 to 31.41 weight percent of ZrO2 powder; automatically generating a particle wild phase by using a thermit reaction in the process of generating a matrix phase to obtain an Al2O3 dispersed phase reinforced matrix phase Ti2AlC fine crystal composite material; and performing solid solution strengthening on a matrix by using Zr generated by the reaction. The material has high component adjustability, a low sintering temperature, a uniform and compact structure, lower cost and a high mechanical property, so that the application range of the composite material is widened; in addition, by the method, sintering temperatures and hot-pressing pressure are reduced, and crystal grain micritization is realized in the quick sintering process.

Description

technical field [0001] The invention belongs to the field of composite material manufacturing, in particular to a (Ti, Zr) 2 AlC / Al 2 o 3 . Solid solution composite material and its preparation method. Background technique [0002] New Layered Ceramic Material Ti 2 AlC has attracted the exploration and research of many scholars at home and abroad for its excellent properties. It not only has the properties of metals, such as good electrical and thermal conductivity at room temperature, low Vickers hardness, high elastic modulus and shear modulus, and can be processed by traditional machining at room temperature. It is plastic at high temperature; the material also has the properties of ceramics, such as high melting point, high thermal stability and good oxidation resistance. However, this material also has disadvantages such as high sintering temperature, small temperature range, low hardness, and low strength, which limit its further application. [0003] In recent y...
