POWDER MIX FOR PRODUCTION OF TITANIUM ALLOY, TITANIUM ALLOY MADE THEREOF AND METHODS OF THEIR FABRICATION Russian patent published in 2016 - IPC B22F1/00 B22F3/15 C22C1/04 C22C14/00 

FIELD: metallurgy.

SUBSTANCE: group of inventions relates to powder metallurgy. Claimed mix comprises the titanium alloy powder containing aluminium and vanadium or, additionally, one element of zirconium, tin, molybdenum, iron and chromium, and at least one metal powder selected from powders of copper, chromium and iron, mixed with titanium alloy powder. Note here that titanium alloy powder is produced by titanium alloy stock hydrogenation and dehydrogenation of obtained hydrogenated stock. The amount of metal powder makes 1-10 wt % at addition of one type of metal powder. At addition of two or more types of metal powders the amount of added metal powder makes 1-20 wt %. This invention disclosed also the production of said powder mix, titanium alloy and its production thereof.

EFFECT: higher quality of powder mix, mix density increased to at least 99% of theoretical value.
