ALLOY CLOSE TO BETA-TITANIUM FOR APPLICATIONS REQUIRING HIGH STRENGTH, AND ITS MANUFACTURING METHODS Russian patent published in 2013 - IPC C22C14/00 C22F1/18 B64C25/00 

FIELD: metallurgy.

SUBSTANCE: high-strength pseudo-beta titanium alloy contains the following, wt %: aluminium 5.3-5.7, vanadium 4.8-5.2, iron 0.7-0.9, molybdenum 4.6-5.3, chrome 2.0-2.5, oxygen 0.12-0.16, and titanium and impurities are the rest, and when necessary, one or more additional elements chosen from N, C, Nb, Sn, Zr, Ni, Co, Cu and Si; with that, each additional element is present in the amount of less than 0.1%, and total content of additional elements is less than 0.5 wt %. At production of alloy, after it is obtained, homogenisation is performed at the temperature below temperature of beta-conversion and its disperse strengthening. An aviation system component represents a landing gear or a fastening part, which is made using titanium alloy.

EFFECT: alloy has high strength,ductility and ability for deep hardening.
