Abstract

The invention relates to the making of TiAl based composite material with reinforced three dimensional net structure Ti2AlC. It solves the poor indoor plasticization and low strength issue of existing material. The newly invented material is made in the following combination based on atomic percentage: Ti powder 45-50at.%, Al powder 40-49at.%, 1-15at.% of one or more of Nb,Cr,Mn,V, Ni,W,Ta,Mo,Zr,Si,B powders, and carbon nanometer tube with the total weight of Ti, Al and element powder 0.05-20%, with two or more of Nb,Cr,Mn,V,Ni,W, Ta,Mo,Zr,Si,B, with all the element powders in random atomic percentages. It is made through ball grinding, mixing powder after feeding carbon nanometer tube, plasma sintering to get the final product.

Description

technical field [0001] The invention relates to a TiAl-based composite material and a preparation method thereof. Background technique [0002] TiAl metal is widely used in the fields of aerospace, aviation and automobile manufacturing. However, due to the poor room temperature plasticity and poor thermal processing ability of TiAl metal, this material cannot be widely used in engineering. Scientists at home and abroad have done a lot of research on the structure, plasticity and deformation of TiAl metal compounds. Studies have shown that TiAl-based composites have high specific elastic modulus, high specific strength, high creep resistance and high strength, high stiffness self-generated reinforcement phase, room temperature plasticity and hot workability can also be enhanced; but the original TiAl-based composites have the problems of poor room temperature plasticity and low strength. Contents of the invention [0003] The invention aims to solve the problems of poor m...
