Claims
- 1. A cutting tool prepared from a composition comprising a refractory metal carbide and a ductile Ni.sub.3 Al alloy.
- 2. A cutting tool prepared from a composition comprising a ceramic material and a ductile metal alloy selected from the group consisting of alloys of Ni.sub.3 Al, TiSi.sub.2, NiSi, MoSi.sub.2, and mixtures thereof.
- 3. A process for the preparation of a cemented carbide article having a composition comprising a ceramic material and a ductile metal alloy selected from the group consisting of alloys of Ni.sub.3 Al, TiSi.sub.2, NiSi, MoSi.sub.2, and mixtures thereof, the process comprising;
- (a) blending powders of the ceramic material and the ductile metal alloy to form a mixture; and
- (b) consolidating the mixture under conditions of temperature and pressure such that a densified cermeted carbide article is produced, the process being conducted in the absence of a metal leaching step.
