ATI 64-MIL™ titanium alloy (UNS R56400) is a two phase alpha+beta titanium alloy, with aluminum as the alpha stabilizer and vanadium as the beta stabilizer. This high-strength alloy can be used at cyrogenic temperatures to about 800° F (427° C). ATI 64-MIL™ alloy is used in the annealed condition and in the solution treated and aged condition. Some applications include: armor, compressor blades, discs, and rings for jet engines; airframe and space capsule components; pressure vessels; rocket engine cases; helicopter rotor hubs; fasteners; critical forgings requiring high strength-to-weight ratios; medical and surgical devices. This alloy is produced by primary melting using vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Remelting is achieved by one or two vacuum arc steps.
