FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, specifically to alpha/beta titanium alloys with high strength and ductility. Alpha/beta titanium alloy contains, wt%: from 3.9 to 4.5, aluminium, from 2.2 to 3.0 vanadium, from 1.2 to 1.8 iron, from 0.24 to 0.30 oxygen, up to 0.08 carbon maximum, up to 0.05 nitrogen maximum, up to 0.015 hydrogen maximum, a total of up to 0.30 other elements: less than 0.005 of each of boron and yttrium, not more than 0.10 of each of tin, zirconium, molybdenum, chromium, nickel, silicon, copper, niobium, tantalum, manganese and cobalt, and balance is titanium and unintentional impurities.
EFFECT: alloy is characterized by high mechanical properties with reduced weight.
