Abstract

T3SiC2 is a typical Mn+1AXn (MAX) phase ceramics and shows unique metallic-like and ceramic-like properties. To improve these properties, texturing and Al2O3 addition have been conducted. The commercial T3SiC2 powder used contains approximately 10 wt% TiC phase. Textured T3SiC2 was prepared by slip cast in strong magnetic fields followed by spark plasma sintering (SPS) at 1350°C under 40 MPa for 5 min. The Lotgering orientation factor of (00l) peaks of T3SiC2 with magnetic field (MF) was 0.96, and relative density of samples was beyond 99%. The bending strength and fracture toughness of T3SiC2 were improved by texturing. T3SiC2 with magnetic field showed excellent value of bending strength of 978 MPa, but Al2O3 addition caused deterioration of bending strength and fracture toughness. T3SiC2 with MF showed the plastic deformation at temperature at around 900°C.
