Description
A method for preparing high-purity Ti2AlC bulk material technical field The invention relates to a preparation method of Ti2AlC. Background technique Ti2AlC is a new type of ternary layered compound. It not only has many advantages of ceramics, such as high modulus (Young's modulus 277.6GPa, shear modulus 118.8GPa), high strength, etc., but also has some properties of metals, such as low hardness, machinability, good conductivity Thermal conductivity, high damage tolerance. Ti2AlC has a very low density (theoretical density 4.11g / cm2) and excellent oxidation resistance, so it can be used as a high-temperature structural material. As a new structure / function integrated material, Ti2AlC has a wide application space in the fields of aviation, aerospace, electronics industry and nuclear industry. Although Ti2AlC has many excellent comprehensive properties and broad application prospects, the preparation of Ti2AlC is extremely difficult, which limits its related basic resear...
