| Outline of Final Research Achievements |
The purpose of this research is to fabricate high-performance ternary carbon nitride ceramics using ubiquitous elements by texturing.
Texture Ti3SiC2 and alumina dispersed Ti3SiC2 were successfully prepared by slip casting under a strong magnetic field followed by pulsed current sintering. Both bending strength and fracture toughness of Ti3SiC2 have been improved by texturing and alumina addition. In addition textured Ti2AlN shows higher bending strength, fracture toughness and wear resistance than those of non-textured Ti2AlN.New types of stable phase of MAX phase ceramics with X=B and two-dimensional transition metal carbides, Mxenes, were demonstrated to show unique properties by calculations.
