摘要： PROBLEM TO BE SOLVED: To provide a cermet excellent in defect resistance and abrasion resistance, a cutting tool using the cermet, and a manufacturing method of the cermet.
SOLUTION: The cermet has a constitution where hard phases, which each include a cored particle 10a composed of a core part 11 essentially comprising TiCN and a peripheral part 12 surrounding the core part 11 and comprises a titanium composite compound, are bound to each other via a binder phase 20 essentially composed of an iron group metal such as Co. A W-enriched phase containing a large amount of W exists in a region near the core part, i.e. within 200 nm from a boundary 13 between the core part 11 and the peripheral part 12. The cermet is excellent in abrasion resistance due to the presence of cored particle 10a and is excellent in toughness because propagation of cracks formed near the boundary 13 can be suppressed due to the presence of the W-enriched phase near the boundary 13.

摘要： PROBLEM TO BE SOLVED: To provide a cemented carbide having excellent strength and thermal crack resistance, to provide a coated cutting tool using the cemented carbide as a base material, and to provide a method for producing the coated cutting tool. SOLUTION: Disclosed is a cemented carbide in which WC particles are bonded with a bonding phase including Co, and, regarding a region composed of the bonding phase in the cross-section, at least either condition that the Σ3 crystal grain boundary length per 100 square micron is 0.3 to 30 μm or that the ratio of the Σ3 crystal grain boundary length to the whole crystal grain boundary length per 100 square micron is 0.03 to 3% is satisfied. Since the Σ3 crystal grain boundary length satisfies the above specified range, the sliding of an atomic plane caused by the inconsistency of crystals is hard to occur, thus the cemented carbide has excellent plastic deformation resistance, and also, by introducing strains or the like into the grain boundaries, its strength and toughness can be improved.
