采用强磁场定向放电等离子烧结（SMFA）技术成功制备了织构化Ti 3AlC 2陶瓷。约15体积% Al_2O_3颗粒在此过程中原位形成。获得了1261 MPa（//caxis）的优异弯曲强度和14.6 MPa m1/2（/caxis）的断裂韧性的独特组合。此外，高电导率和热导率分别测定为1.0 × 106Ω− 1 m −1（//caxis）和25.3 W（m K）−1（caxis）。
Textured Ti3AlC2ceramic was successfully fabricated by a strong magnetic field alignment (SMFA) technique followed by spark plasma sintering (SPS). About 15 vol.% Al2O3particles were formedin situduring the process. The unique combination of excellent bending strength of 1261 MPa (//caxis) and fracture toughness of 14.6 MPa m1/2(⊥caxis) was achieved. Also, the high electrical and thermal conductivities were determined as 1.0 × 106Ω−1m−1(//caxis) and 25.3 W (m K)−1(⊥caxis), respectively.
