Abstract
Titanium alloys with an improved and unexpected combination of corrosion resistance, strength, ductility and toughness are provided. The titanium alloys contain molybdenum, nickel, zirconium, iron, and oxygen as alloying agents. Also the titanium alloys may be subjected to thermal treatments. The titanium alloys can include molybdenum between 3.0 to 4.5 wt. %, nickel between 0.1 to 1.0 wt. %, zirconium between 0.1 to 1.5 wt. %, iron between 0.05 to 0.3 wt. %, oxygen between 0.05 to 0.25 wt. %, and a balance of titanium and unavoidable impurities. The titanium alloys can have a yield strength between 550 to 750 MPa, a tensile strength between 700 to 900 MPa, an elongation to failure between 25 to 35%, a reduction in area between 55 to 70%, and a corrosion rate between 0.5 to 2.5 mils per year when exposed to 1 wt. % boiling hydrochloric acid per the ASTM G-31 test method.
