Titanium alloy having good oxidation resistance and high strength at elevated temperatures

A titanium alloy may be characterized by a good oxidation resistance, high strength and creep resistance at elevated temperatures up to 750° C., and good cold/hot forming ability, good superplastic forming performance, and good weldability. The alloy may contain, in weight percent, aluminum 4.5 to 7...

More Information
Summary:A titanium alloy may be characterized by a good oxidation resistance, high strength and creep resistance at elevated temperatures up to 750° C., and good cold/hot forming ability, good superplastic forming performance, and good weldability. The alloy may contain, in weight percent, aluminum 4.5 to 7.5, tin 2.0 to 8.0, niobium 1.5 to 6.5, molybdenum 0.1 to 2.5, silicon 0.1 to 0.6, oxygen up to 0.20, carbon up to 0.10, and balance titanium with incidental impurities.
