Abstract:
A method of producing a high strength, high stiffness and high ductility titanium alloy, comprising combining the titanium alloy with boron so that the boron concentration in the boron-modified titanium alloy does not exceed the eutectic limit. The carbon concentration of the boron-modified titanium alloy is maintained below a predetermined limit to avoid embrittlement. The boron-modified alloy is heated to a temperature above the beta transus temperature to eliminate any supersaturated excess boron. The boron-modified titanium alloy is deformed at a speed slow enough to prevent microstructural damage and reduced ductility.
