Abstract

Disclosed are a plate-crystalline tungsten carbide-containing hard alloy which comprises 4 to 40% by volume of a binder phase containing at least one of iron group metals selected from Co, Ni and Fe as a main component; and the balance of a hard phase comprising tungsten carbide alone, or tungsten carbide and 50% by volume or less of a compound with a cubic structure selected from at least one of carbide and nitride of the 4a(Ti, Zr and Hf), 5a(V, Nb and Ta) or 6a(Cr, Mo and W) group element of the periodic table and mutual solid solutions thereof, and inevitable impurities, wherein when peak intensities at a (001) face and a (101) face in X-ray diffraction using Kalpha rays with Cu being a target are represented by h(001) and h(101), respectively, the tungsten carbide satisfies h(001)/h(101) ≥ 0.50, a composition for forming a plate-crystalline tungsten carbide, and a process for preparing the plate-crystalline tungsten carbide-containing hard alloy.
