HIGH-TEMPERATURE TITANIUM ALLOYS Russian patent published in 2022 - IPC C22C14/00 C22F1/18 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to high-temperature titanium alloys. The titanium alloy contains, in mass percent based on the total weight of the alloy: from 5.5 to 6.5 aluminum, from 1.9 to 2.9 tin, from 1.8 to 3.0 zirconium, from 4.5 to 5 .5 molybdenum, 4.2 to 5.2 chromium, 0.08 to 0.15 oxygen, 0.03 to 0.20 silicon, more than 0 to 0.30 iron, titanium and impurities. Titanium alloy has an aluminum equivalent value from 8.0 to 9.5, which is determined by the following expression: Al_eq=Al_wt.%+(1/6)×Zr_wt.%+(1/3)×Sn_wt.%+10×O_wt..%.

EFFECT: alloy is characterized by high creep resistance as well as high tensile strength at elevated temperatures.
