| Research Abstract |
To develop high-hardness and high-fracture-toughness ceramics, Ti C-based ceramics were synthesized and consolidated by reaction hot-pressing of BN-Ti-TiC-SiC or TiC-SiC-TiSi_2 powder mixtures. For BN-Ti-TiC-SiC powder mixtures, Ti(C, N)-TiB_2-Ti_5Si_3C_x were synthesized. These ceramics had hardness values below 20 GP_a. For 0.5TiC-0.5SiC-(0.05-0.15)TiSi_2 powder mixtures, dense TiC-SiC-Ti_3SiC_2 ceramics were produced. These ceramics showed good sinterability and were excellent in mechanical properties: hardness 21-22 GPa and fracture toughness 6 MPa _m^<1/2>.
