Abstract
Sintering of a mixture of alumina and titanium carbide has been difficult heretofore, but by the intermediary action of titanium oxides, sintering of a powder mixture consisting of alumina and titanium carbide by hot-pressing at a comparatively lower temperature than that used in conventional processes becomes possible. Various procedures in which the above principle is applied, the powder mixture to be used therein and the materials produced thereby which are to be used for manuacturing cutting tools are disclosed.
