Abstract

Sintered hard alloys are produced from a powdered mixture comprising tungsten carbide and up to 30 per cent of one or more alloys of iron nickel or cobalt with one of the metals titanium, zirconium, hafnium, tantalum, niobium, vanadium or molybdenum, the mixture being sintered at a high temperature, e.g. 1400-1700 DEG C. for the time necessary for the production of the final alloy. The sintering may be carried out in an indifferent atmosphere. The alloys of iron &c. are produced by mixing the two components in stoichometric proportions and sintering the mixture in hydrogen at 1200-1600 DEG C.
