FIELD: metallurgy; methods of production of refractory metal alloys.
SUBSTANCE: proposed method includes alumino-thermal reduction of compounds of refractory metals. Compounds of refractory metals at different oxidation are introduced into charge; abrasion and mixing of charge materials are continued till the following fractional composition has been obtained: particles at size of 0.6-1.2 mm, no less than 75%; particles at size more than 1.2 mm, no more than 5%; particles at size no less than 0.6 mm, no more than 20%.
EFFECT: facilitated procedure; optimization of temperature conditions; increased extraction of metal into alloy.
