摘要：
An alpha/beta titanium alloy comprising, in percent by weight based on total alloy weight: 3.9 to 4.5 aluminum； 2.2 to 3.0 vanadium； 1.2 to 1.8 iron； 0.24 to 0.30 oxygen； up to 0.08 carbon； up to 0.05 nitrogen； up to 0.015 hydrogen； titanium； and up to a total of 0.30 of other elements. A non-limiting embodiment of the alpha/beta titanium alloy comprises an aluminum equivalent value in the range of 6.4 to 7.2, exhibits a yield strength in the range of 120 ksi (827.4 MPa) to 155 ksi (1,069 MPa), exhibits an ultimate tensile strength in the range of 130 ksi (896.3 MPa) to 165 ksi (1,138 MPa), and exhibits a ductility in the range of 12 to 30 percent elongation.
