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 composite sintered compact in which a cemented carbide layer and a cermet layer are laminated, and to provide a method for producing the same. SOLUTION: A cemented carbide powder composing a cemented carbide layer and a cermet powder composing a cermet layer are prepared as raw material, and these powders are laminated so as to produce a molded body, and the molded body is sintered so as to produce a composite sintered compact 10 in which the cemented carbide layer 12 and the cermet layer 11 are laminated. As the cermet powder, the powder of a solid solution containing Ti and W and having a cored structure is used by ≥10 mass%. By utilizing the powder of the solid solution having the specified composition and the cored structure, compared with the case where the powder of a solid solution having no cored structure or a powder which has not be made into a solid solution, its wettability with a bonding phase can be increased, and its sintering property can be improved. As a result, deformation caused by a difference in a shrinkage behavior upon sintering between the cemented carbide and cermet is suppressed, and a composite sintered compact with a proper shape is easily obtainable.
