TITANIUM-BASED ALLOY Russian patent published in 2014 - IPC C22C14/00 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, and namely to titanium-based alloys, and can be used in equipment components of chemical productions, in welded connections of shipbuilding industry. Titanium-based alloy contains the following, wt %: aluminium 4.3-6.3, molybdenum 1.5-2.5, carbon 0.05-0.14, zirconium 0.2-1.0, oxygen 0.06-0.14, silicon 0.02-0.12, iron 0.05-0.25, niobium 0.3-1.20, ruthenium 0.05-0.14, and titanium is the rest. Total content of silicon and iron shall not exceed 0.30 wt %.

EFFECT: alloy has increased stability to crevice and pitting corrosion in corrosive media with increased salt content and at the temperature of up to 250 °C.
