METHOD OF METAL PRODUCT MANUFACTURE WITHOUT MELTING Russian patent published in 2017 - IPC B22F3/02 B22F9/18 

FIELD: metallurgy.

SUBSTANCE: method of metal product manufacture based on the titanium alloy includes nonmetallic precursor compounds mixture preparing, containing the metal constituents in finely divided form with the maximum size of less than 100 microns in which the titanium content is greater than any other metal element, chemical reduction of the nonmetallic compounds precursors mixture, to obtain the initial metal material in the form of the powder without melting the initial metallic material. The chemical reduction stage involves the chemical reducing of the nonmetallic precursor compounds mixture in the solid phase, by vapour phase reduction or the oxides reduction by the molten salt electrolysis and compacting of the resulting reduced material to produce the compacted metal product, without melting the initial metallic material and without melting the compacted metal product.

EFFECT: improvement of the products mechanical characteristics, made of titanium-based alloys.
