摘要:
A cemented carbide composed of a first hard phase, a second hard phase and a binder phase, in which the first hard phase is composed of tungsten carbide particles, the second hard phase is composed of at least one first compound selected from the group consisting of TiNbC, TiNbN and TiNbCN, the second hard phase has an average particle diameter of no more than 0.1 μm, the second hard phase has a dispersity of no more than 0.7, the second hard phase has a content of no less than 0.1 vol % and no more than 15 vol %, the binder phase contains at least one first element selected from the group consisting of iron, cobalt and nickel, and the binder phase has a content of no less than 0.1 vol % and no more than 20 vol %.
