Abstract:
1. A method of producing a high strength, high stiffness and high ductility titanium alloy, the method comprising: alloying a titanium alloy with boron so that the boron concentration in the boron-modified titanium alloy does not exceed the eutectic limit; maintaining the carbon concentration of the boron-modified titanium alloy below a predetermined limit to avoid embrittlement of the boron-modified titanium alloy; heating the boron-modified alloy to a temperature above the beta transus temperature to force supersaturated boron out of a titanium lattice of the boron-modified titanium alloy and to increase an inter-particle spacing of a titanium boride microconstituent; and deforming the boron-modified titanium alloy at a speed that avoids damage to the titanium boride microconstituent of the boron-modified titanium alloy.
