Titanium-based alloy

Abstract

The inventive titanium-based alloy contains 2.2-3.8 mass % aluminium, 4.5-5.9 mass % vanadium, 4.4-5.9 mass % molybdenum, 2.0-3.6 mass % chromium, 0.1-0.4 mass % zirconium, 0.01-0.18 mass % iron and 0.03-0.25 mass % oxygen, the rest being titanium. Said alloy exhibits a high processing plasticity in hardened condition thereof associated with a high strength. The alloy has a high temperature range, thereby making it possible to use it not only for screw heads and helical springs but also for producing large-sized semi-products whose cross section ranges up to 60 mm and which are used in high temperature conditions.

1 . Alloy with the base of titanium, containing aluminum, vanadium, molibdenum, chromium, iron, zirconium, carbon, oxygen, differing in the fact that the alloy components are taken in the following ratio of the % by weight.
