ABSTRACT:
The alloy of the invention is of the type wherein 30-70% by volume of hard components are homogeneously dispersed in a matrix of binder metal (Fe, Co or Ni). The hard components are carbides or carbonitrides and/or borides of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and/or W. The mean grain size of the hard component particles is between 0.01 and 1.0 micron and their grain size distribution, represented by the standard deviation S, in which S.sup.2 .ltoreq.(M/1+1.5 M.sup.z).sup.2 .mu.m.sup.2, not more than 15% of the grains are larger than 1.2 microns.
