Abstract
An improvement in a cemented hard metal is disclosed. A molybdenum-tungsten-carbonitride is disclosed having the structure of tungsten carbide wherein the molybdenum and/or tungsten are at least partly substituted for by a metal selected from the group consisting of Cr, Nb, Ta, V, Re and mixtures thereof. The carbonitride may be mixed with a binder metal and sintered in a conventional manner to form a dense, substantially pore-free material.
