(57) [Summary] [Purpose] Toughness and hardness can be significantly improved, We provide titanium compound sintered bodies suitable for various cutting tools and other wear resistant parts and ornaments. [Structure] At least one of titanium compounds consisting of titanium carbide, nitride, boride and carbonitride is used for 5 to 90 A titanium compound sintered body containing, as a main component, 5% to 95% by volume of at least one of cubic boron nitride and wurtzite type crystalline boron nitride, wherein a part or all of the titanium compound is a whisker. is there. 0.1% by volume of at least one of aluminum nitride and titanium boride in the sintered body. It is desirable to contain the above. |
