Abstract

A hard alloy consists of 50 per cent or more by weight of titanium carbide and an auxiliary metal, for example iron, cobalt, nickel or their alloys or alloys of cobalt, chromium, and tungsten with or without carbon. The titanium carbide may be supplemented by about 10-20 per cent of other carbides such as tungsten, molybdenum or tantalum carbides. The pulverized carbide is mixed with the powdered auxiliary metal, pressed to form the final body and then heated to a high temperature preferably in hydrogen, or an inert atmosphere or in vacuo. The bodies may also be heated first to a moderate temperature to render them easily workable and then finished by heating to the high consolidation temperature. Chemical compounds of the auxiliary metals, for example, oxides or oxalates may be pulverized or brought into solution, then mixed with the titanium carbide and heated in a reducing atmosphere to obtain a finer distribution of the auxiliary metal in the carbide, the mixture being then consolidated at the higher temperature. In another method the bodies are pressed out from the titanium carbide with or without a small addition of the auxiliary metal and sintered at a high temperature. The porous sintered body is brought into contact with the auxiliary metal and heated so that the molten metal is absorbed by the sintered body. Reference has been directed by the Comptroller to Specification 361,363.
