Abstract

This specification covers the requirements for wrought titanium-6aluminum-4vanadium alloy for use in surgical implant applications. The material shall be manufactured by multiple melting in plasma arc and electron beam furnaces into strip, sheet, plate, bar, forging bar, or wire. The material shall be available in the annealed or cold-worked condition, with the surface mechanically descaled or pickled, sandblasted, chemically milled, ground, machined, peeled, polished, or a combination of these. Heat and product analyses as well as tension and bend (for sheet, strip, and plate) tests shall be performed and shall conform to the requirements specified. In addition, the material shall have a microstructure consisting of a fine dispersion of alpha and beta phases as a result of processing in the alpha plus beta field, with no continuous alpha network at prior beta grain boundaries and no coarse, elongated alpha platelets.
