Abstract

A sintered metallic body containing a dispersed refractory phase is formed by compacting and sintering a slurry composed of one or more metal powders in a solution of a soluble compound containing at least one of the elements of the refractory phase, another substance being added to the slurry to react with the compound and form a precipitate which is decomposed by heat to form the said refractory phase. The refractory phase is a refractory oxide or oxides such as Al2 O3, Mg O, Si O2, Be O, or Th O2 and forms 1% to 15% by volume of the body. The oxides may be dispersed in Ni, Cu or alloys by precipitating the metallic hydroxide from a slurry of the aqueous solution of the refractory metallic halide and a metal or alloy, by means of aqueous ammonium hydroxide. After drying the slurry is compacted at 10 Tons/sq. inch and sintered in vacuum or an inert or reducing atmosphere at 1400 DEG C. The sintered compacts may then be cold worked.
