摘要： A method of making an alpha-beta titanium alloy is provided. The method includes forming a melt and solidifying the melt to form an ingot. The melt composition includes concentrations of Al from about 4.7 wt. % to about 6.0 wt. %; V from about 6.5 wt. % to about 8.0 wt. %; Si at less than 1 wt. %; Fe at up to about 0.3 wt. %; 0 at less than 1 wt. %; and a balance of Ti and incidental impurities. Furthermore, the Al/V ratio in the melt is equal to the concentration of the Al divided by the concentration of the V in weight percent is from about 0.65 to about 0.8.

摘要： Titanium alloys formed into a part or component used in applications where a key design criterion is the energy absorbed during deformation of the part when exposed to impact, explosive blast, and/or other forms of shock loading is described. The titanium alloys generally comprise a titanium base with added amounts of aluminum, an isomorphous beta stabilizing element such as vanadium, a eutectoid beta stabilizing element such as silicon and iron, and incidental impurities. The titanium alloys exhibit up to 70% or more improvement in ductility and up to a 16% improvement in ballistic impact resistance over a Ti-6Al-4V alloy, as well as absorbing up to 50% more energy than the Ti-6Al-4V alloy in Charpy impact tests. A method of forming a part that incorporates the titanium alloys and uses a combination of recycled materials and new materials is also described.

摘要： 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.
