Abstract

A sintering method for a W--Ni--Mn type heavy alloy, including controlling the deoxidization of tungsten and nickel under an inert atmosphere, changing to a hydrogen atmosphere at above a temperature at which manganese is deoxidized and simultaneously deoxidizing tungsten, nickel and manganese, and sintering by raising the temperature, resulting in the fabrication of a sintered heavy alloy having a 100% relative theoretical density.
