Abstract:
A non-limiting embodiment of a titanium alloy comprises, in weight percentages based on total alloy weight: 2.0 to 5.0 aluminum; 3.0 to 8.0 tin; 1.0 to 5.0 zirconium; 0 to a total of 16.0 of one or more elements selected from the group consisting of oxygen, vanadium, molybdenum, niobium, chromium, iron, copper, nitrogen, and carbon; titanium; and impurities. A non-limiting embodiment of the titanium alloy comprises an intentional addition of tin and zirconium in conjunction with certain other alloying additions such as aluminum, oxygen, vanadium, molybdenum, niobium, and iron, to stabilize the α phase and increase the volume fraction of the α phase without the risk of forming embrittling phases, which was observed to increase room temperature tensile strength while maintaining ductility.
