Ti₂AlC/TiAl composites with a network structure were successfully prepared with carbon nanotubes and Ti-45Al-8Nb pre-alloyed powder using spark plasma sintering. The effects of sintering temperature (1200-1350 °C) on the microstructural evolution and mechanical properties were systematically investigated. The microstructure of Ti₂AlC/TiAl composites exhibits duplex, near-lamellar, and fully lamellar structures, as the sintering temperature increases from 1200 to 1350 °C. The network structured Ti₂AlC phase can refine the microstructure and the phase becomes discontinuous at high sintering temperatures. Notably, composites sintered at 1300 °C exhibit excellent mechanical properties, with the highest compressive strength (1921 MPa) and fracture strain (26%) at room temperature. Moreover, the ultimate tensile strength and fracture strain reach 537 MPa and 3.1% at 900 °C, and 485 MPa and 3.3% at 950 °C, respectively. The enhancement of the mechanical properties is attributed primarily to the load bearing, particle pull-out, and inhibition of crack propagation induced by Ti₂AlC particles.
