Tailoring Ti3AlC2 ceramic with high anisotropic physical and mechanical properties
Journal of the european ceramic society, 2015•Elsevier
Abstract Textured Ti 3 AlC 2 ceramic was successfully fabricated by a strong magnetic field
alignment (SMFA) technique followed by spark plasma sintering (SPS). About 15 vol.% Al 2
O 3 particles were formed in situ during the process. The unique combination of excellent
bending strength of 1261 MPa (//c axis) and fracture toughness of 14.6 MPa m 1/2 (⊥ c axis)
was achieved. Also, the high electrical and thermal conductivities were determined as 1.0×
10 6 Ω− 1 m− 1 (//c axis) and 25.3 W (m K)− 1 (⊥ c axis), respectively.
