FIELD: metallurgy. SUBSTANCE: hydrogen absorption of alloy is carried out. Then heating to temperature being by 20-50 C lower than end point of (α+β)/β-transition followed by standing within 1 h takes place. Then cooling to temperature being by 200-400 C higher than end point of reverse transition is carried out, its rate being 0.03-10 C/s. Ageing at mentioned above temperature within 1-10 h is carried out, it is followed by final vacuum roasting at 600-650 C. Time lag is so that provides complete degassing. EFFECT: increases strength of 
-alloys, decreases weight of desired articles. 1 tbl
