A method for producing a Ti-6Al-4V article, includes providing a work piece of a Ti-6Al-4V alloy having a beta-transus temperature; subjecting the work piece to a beta solution heat treatment process in a furnace with a vacuum at a temperature above the beta transus; quenching the work...
(niobium), and Ti–6Al–4V. The first two wires are beta-Ti alloys; Nb is also a beta-stabilizing element. The Ti–6Al–4V wire has an alpha-beta microstructure. The hexagonal close-packed α-phase is the lower-temperatureatomic arrangementof Ti, and Al is an alpha-stabilizing element....
Duerig and Williams1 used the following operational definition of a beta titanium alloy: “A β-Ti alloy is any titanium composition which allows one to quench a very small volume of material into ice water from above the material’s β-transus temperature without martensitically decomposing the...
The alloy Ti–6/4 is usually produced in ingot form by vacuum arc melting of consumable electrodes. The as-cast structure is broken down by forging at 100–150 °C above the β-transus. On cooling to room temperature the α-phase precipitates on β-phase grain boundaries and Widmanstatten...
. Above the beta transus temperature, the microstructure changes to the beta phase, which has a body-centered-cubic crystal structure. Certain alloying elements may be added to control the microstructure and thereby allow the beta phase to be at least metastable at room temperature. Alpha-beta ...
Ti–6Al–4V is an alloy increasingly used for structural applications in aeronautics due to its characteristics of high mechanical properties, lightness, and corrosion resistance. This alloy is conventionally forged below the beta transus temperature in order to control the microstructure evolution, to ...

the alloys may be strengthened by rapid cooling from a high temperature in the alpha-beta range or above the beta transus temperature. This procedure, known as solution treatment, is followed by an intermediate-temperature treatment, termed aging, to result in a desired mixture of alpha and tra...
