ABSTRACT:
The present invention is a process for making shaped, dense, hard, fine grain tool quality tungsten carbide by the interaction of tungsten, carbon and cobalt during a single heat treatment to form WC + Co compositions. The interaction occurs in situ without the aid of applied pressure. The interaction produces wares of high density with excellent mechanical and cutting properties.
