    摘要： A cemented carbide body is 1-30% by mass of binder consisting of Co, Co/Ni, Co/Fe, Co/Ni/Fe or Ni/Fe and a hard material having a hexagonal WC phase and having a face-centered cubic phase of the form (M1, M2, M3)C or (M1, M2, M3)(C, N) or (M1, M2, M3)(O, C, N) where M1=Ti and/or Zr and M2=W and M3 optionally means none or one or a plurality of the elements Ta, Nb, Hf, Cr, Mo or V, wherein the proportion of the face-centered cubic phase based on the total mass is 2% to 97%, preferably 5 to 12% by mass, and the microstructure of the hexagonal phase and of the face-centered cubic phase has a mean grain size of between 0.2 μm and 1 μm, preferably ≦0.9 μm, and the mean grain sizes of the hexagonal phase and of the face-centered cubic phase differ at most by 30%.
