摘要
Cermet contains a hard phase which contains carbonitride containing Ti and Nb and a metallic binder phase containing an iron-group element. The hard phase 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 composed to be higher in content of W than the core portion.
