摘要

A hard alloy including at least one hard phase and a binary or multicomponent binder metal alloy, in which the hard substance comprises a finely dispersed, homogeneous distribution in the binder metal. The hard phase comprises a carbide of a Group IVb, Vb or VIb transition metal, and the binder metal alloy comprises a solid alloy of a Group IVb, Vb or VIb transition metal, with Re, Ru, Rh, Pd, Os, Ir, or Pt.
