Abstract
This invention relates to nonferrous metallurgy, namely to manufacture of near-beta titanium alloys containing titanium and such alloying elements as molybdenum, vanadium, chromium, zirconium, iron and aluminum. The provided alloy contains the following components, in weight percentages: molybdenum—25 to 27; vanadium—25 to 27; chromium—14 to 16; titanium—9 to 11; with balance aluminum and iron and zirconium in the form of commercially pure metals. The technical result of this invention is capability to produce a near-beta titanium alloy with high chemical homogeneity alloyed by refractory elements and having aluminum content ≦6 wt %, wherein the alloy is characterized by a combination of stable high strength and high impact strength.
