FIELD: metallurgy.
SUBSTANCE: method of processing the titanium alloy consisting of, at least, the following components, in wt %: iron - 0.2-0.5, oxygen - 0.02-0.12, silicon - 0.15-0.6, titanium and unavoidable impurities making the rest, comprises executing the first thermal treatment at first temperature to form the structure containing 50% of beta-phase, and, then, cold rolling. Second thermal treatment at second temperature is executed to produce second-phase precipitation while third thermal treatment is performed at third temperature for alloy recrystallisation without dissolution of precipitation.
EFFECT: high-strength titanium alloy with high resistance to oxidation and pliability at low temperatures.
