Abstract

Ti3SiC2 is a typical Mn+1AXn (MAX) phase ceramics and shows unique metallic-like and ceramic-like properties. To improve these properties, texturing and oxide addition have been conducted. Textured Ti3SiC2 and 10 vol% Al2O3/Ti3SiC2 were prepared by slip cast in strong magnetic fields followed by SPS at 1350°C. The Lotgering orientation factor of textured Ti3SiC2 and textured Ti3SiC2/Al2O3 were 0.91, 0.88 respectively, and relative density of both samples was nearly 98%. The Bending strength of Ti3SiC2 was improved by Al2O3 addition, and the fracture toughness of Ti3SiC2/Al2O3 was improved by texturing. Both textured Ti3SiC2 and textured Ti3SiC2/Al2O3 showed the plastic deformation at temperature about 800°C.
