Abstract
This invention relates to a hard alloy consisting of a metallic phase and a hard phase having a B1 type crystal structure, and being represented by the following general formula, (M1a, M2b, M3c)(C1-x-yNyOx)z in which M1 is at least one of Group IVa elements, M2 is at least one of Group VIa elements, M3 is at least one of Group Va elements, C is carbon, N is nitrogen, O is oxygen, a, b, c, x and y are respectively atomic ratios satisfying the relations of a + b + c = 1, 0.1 </= (a + c)/(a + b + c) </= 0.7 (c can be zero), 05 </= x </= 0.5, 0 </= y </= 0.5 0.05 </= x + y </= 0.6 and z is an atomic ratio of (C + N + O)/M1 + M2 + M3) satisfying the relation of 0.1 </= z </= 0.5. Small amounts of Fe, Co, Ni, Ag, Cu, Pd, K, Ca, Ma, Si, Al, Re or Th may be present as sintering additives.
