摘要： PROBLEM TO BE SOLVED: To provide a hard material with a composite structure in which adhesion of grain boundaries is improved, and to provide a method for producing the same. SOLUTION: In the hard material produced by liquid phase sintering, the hard material with a composite structure is produced by simultaneously sintering a hard material layer not including titanium carbide and a hard material layer including titanium carbide, wherein the hard material layer not including titanium carbide contains one or more selected from tantalum and niobium. In the method for producing the hard material with the composite structure, a hard material layer not including titanium carbide and a hard material layer including titanium carbide are heated to a temperature at which metals included in both the layers produce liquid phases so as to form a reaction layer on the boundary part of both the layers, thus the quantity of the metals in the grain boundary part is reduced so as to produce the hard material with a composite structure in which the peeling of both the layers is prevented. In this way, the hard material including titanium carbide and the hard material not including titanium carbide are made of different hard materials, thus reaction at the grain boundaries is controlled, and both the hard materials can be simultaneously sintered.

摘要： PROBLEM TO BE SOLVED: To provide a cutting tool having excellent impact resistance and providing good gloss on a finish surface.
SOLUTION: The cutting tool 10 is composed by laminating a cemented carbide layer 11 and a cermet layer 12. The whole rake face is formed of the cemented carbide layer 11, and a flank face is formed of an laminated surface of the cemented carbide layer 11 and the cermet layer 12. At a cutting blade part (a corner part of the cutting tool 10), the cemented carbide layer 11 is thin. When h1 is the maximum thickness of the tool 10, and h2 is the maximum thickness of the cemented carbide layer existing in the cutting blade part, h2/h1 satisfies 0.002 or more and 0.02 or less. The cemented carbide layer more excellent in toughness than cermet is provided on the rake face side, which makes the tool resistant to impact due to contact with chips, etc. The high ratio of the cermet layer on the flank face side of the cutting blade part provides the good gloss on the finish surface.
