    Abstract: The invention provides Al2O3 dispersion-strengthened Ti2AlN composites, wherein Ti2AlN matrix and Al2O3 strengthening phase both are reactively formed in situ. The volume fraction of Al2O3 is 5% to 50%; the particle size of Al2O3 ranges from 500 nm to 2 μm, with the mean size of Al2O3 particles about 0.8 μm to 1.2 μm; the shape of Ti2AlN grain is plate-like about 80 nm to 120 nm thick and 0.5 μm to 2 μm long. The composites exhibit excellent deformability at high temperature under compression and flexure stresses, and possess excellent oxidation resistance at 1100° C. to 1350° C. for long time (100 h). The composites show typical metallic conductor behavior and the electrical resistivity at room temperature is 0.3 to 0.8 μΩ·m. The invention also provides a method for preparing the same: First, nanoparticles in Ti—Al binary system were prepared in continuous way by hydrogen plasma-metal reaction (HPMR) using Ti—Al alloy rods with Al content 20% to 60% by atom, or pure Al rods and pure Ti rods. The atmosphere used in HPMR is the mixture atmosphere of nitrogen-containing gas, H2 and Ar, with total pressure of 0.8 to 1.2 atm, wherein volume ratio of H2 and Ar is 1:0.8-1.2, and volume fraction of nitrogen-containing gas is 0 to about 20%. Second, the nanoparticles were compacted by vacuum hot pressing at temperature of 800° C. to 1200° C., pressure of 40 MPa to 60 MPa, time of 4 h to 6 h, and vacuum of 2×10−2 Pa to 5×10−3 Pa.
