| 摘 要： | Ti2AlC bulk material was synthesized by hot pressing of mixture powders of TiC, Ti, Al and active carbon. The phase compositions of resultant product at different temperature were detected by X-ray diffractometer. The microstructures of the samples were observed by SEM. Finally, the mechanical properties and thermal properties of the sample at 1 400 ℃ were measured. The results show that high purity Ti2AlC material with little Ti3AlC2 can be synthesized by hot pressing 0.5TIC/1.5Ti/1.0A1/0.5C at 1 400 ℃. Ti2AlC exhibits high mechanical properties and metallic electrical properties. Its fractm＇e toughness is 7.0 MPa·m^1/2, its flexural strength is 384 MPa at room temperature, and its electrical conductivity is 2.56 × 10^6 Ω^-1·m^-1 at room temperature.
