摘要
A titanium alloy composition is provided. In weight percent (wt.%), the alloy includes 5.7 to 8.0% vanadium, 0.5 to 1.75% aluminum, 0.25 to 1.5% iron, 0.1 to 0.2% oxygen, up to 0.15% silicon, up to 0.1% carbon and less than 0.03% nitrogen is provided. In one form, the titanium alloy has a 0.2% yield strength between 600 to 850 MPa, an ultimate tensile strength between 700 to 950 MPa, a percent elongation to failure between 20 to 30%, a percent reduction in area between 40 to 80%, a Charpy U-notch impact energy between 30 to 70 J, and/or a Charpy V-notch impact energy between 40 to 150 J.
