Abstract
In a process for making hard alloys of the type comprising two p or more hard constituents such as refractory metal carbides and one or more auxiliary metals of lower melting point, each of the hard constituents is separately associated with one or more of the auxiliary metals for example by grinding, and the fractions so formed are afterwards mixed and sintered under pressure at high temperature. For example, 75-97 parts of tungsten carbide may be ground with 3-25 parts of cobalt, and 75-92 parts of titanium carbide with 8-25 parts of nickel; a final sintered product may then be obtained from 90-95 per cent of the tungsten carbide mixture and 5-10 per cent of the titanium carbide mixture.
