METHOD FOR DISPERSION OF MATERIAL BY MELT EXTRACTION Russian patent published in 1996 - IPC

Abstract RU 2061582 C1

FIELD: powder metallurgy, precisely, production of fiber and acicular or flake powder by solidification of melt on the rotating mold. Applicable in production of metals and alloys in microcrystalline state with metastable structure and supersaturated concentration of alloying elements for reduction of macro- and micro-segregations and reduction of grain sizes due to high rate of cooling under excessive atmospheric pressure. SUBSTANCE: method for dispersion of material by melt extraction consists in that the dispersion process is conducted at the pressure of ambient gas medium from 1,1•105 Pa to 3,3•107 Pa. EFFECT: increased cooling rate of material in solidification and improved mechanical and physical characteristics. 1 tbl
