Blended elemental titanium alloys
The high cost and long delivery time required to procure forged or extruded titanium alloy machining blanks has led to an extensive effort to procure lower cost, nearer net shape, shorter lead time machining blanks. This report discusses the mechanical properties of blended elemental P/M Ti-6Al-4V and Ti-6Al-6V-2x alloys where x is either tin or zirconium. These materials are being considered as alternatives to forgings and extrusions. The properties of the Ti-6Al-4V alloy were disappointing; both strength and ductility were considerably below the guaranteed minimums for wrought material. The properties of the Ti-6Al-6V-2Sn material, however, proved to be as good as wrought material. It is recommended that some parts currently made or intended to be made from forgings be evaluated as blended elemental Ti-6Al-6V-2Sn P/M parts.
