FIELD: metallurgy. SUBSTANCE: method involves charging products, made from tantalum and having zero plasticity and operated under vacuum at high temperatures, into furnace in the presence of carbon mineral material; creating vacuum to (1.3310-1.33) Pa; heating to 1700-1900 K; holding and cooling to room temperature. Carbonized aluminum oxide or pelletized graphite may be used as carbon mineral material. Products treated in accordance with such method acquire increased plasticity and may stand 20-30 bendings for an angle of 180 deg. EFFECT: increased efficiency and improved quality of products. 2 cl
