| titleOfInvention | Composite hard sintered body, composite member and cutting tool using the same |
| abstract | An object of the present invention is to provide a composite hard sintered body having excellent fracture resistance and wear resistance, and a cutting tool using the same. Kind Code: A1 A hard crystal particle made of at least one kind of carbide, nitride, or carbonitride selected from the group consisting of metals of Groups 4a, 5a, and 6a of the periodic table is bonded by a bonding metal phase made of an iron group metal. An outer peripheral surface of a long core material 12 made of a hard sintered body is covered with a coating layer 13 made of a material different from that of the core material 12, and the core material 12 is provided near an interface between the core material 12 and the coating layer 13. The binding metal concentration-enriched region x having a higher binding metal concentration than the center of the core material 12 is formed. In particular, the ratio Ds / Dc of the binding metal concentration Ds near the interface of the core material 12 to the binding metal concentration Dc at the center of the core material 12 1.05 or more.
