The second hard-phase particle includes a granular core portion and a peripheral portion which covers at least a part of the core portion. The core portion contains composite carbonitride expressed as Ti1-X-YNbXWYC1-ZNZ, where Y is not smaller than 0 and not greater than 0.05 and Z is not smaller than 0.3 and not greater than 0.6. The peripheral portion is different in composition from the core portion.

摘要： In one aspect sintered cemented carbide articles are described herein which, in some embodiments, exhibit enhanced resistance to wear and thermal fatigue. Further, sintered cemented carbide articles described herein can tolerate variations in carbon content without formation of undesirable phases, including eta phase and/or free graphite (C-type porosity). Such tolerance can facilitate manufacturing and use of carbide grades where carbon content is not strictly controlled. A sintered cemented carbide body described herein comprises a hard particle phase including tungsten carbide and a metallic binder phase comprising at least one of cobalt, nickel and iron and one or more alloying additives, wherein the sintered cemented carbide has a magnetic saturation (MS) ranging from 0% to 73% and no eta phase.

摘要： After an alloy powder including W, Cr, at least one of Ti, Zr, and Hf, and at least one of V, Nb, and Ta is produced, the alloy powder, a powdery carbon material, and a catalyst are heat-treated in the presence of a nitrogen gas. The alloy powder is carbonitrided into a multicomponent ceramics powder, and sintered into a sintered body. Alternatively, a powder of a first substance including at least two of Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr, and W is molded into a molded body. Then, the surface of the molded body is surrounded by a second substance including a metal element which is not contained in the powder of the first substance, and the molded body is heat-treated in an atmosphere in which N is present. A porous sintered body thus produced is crushed into a multicomponent ceramics powder.
