Ti-5553 Wrought Process Optimization

The Ti-5Al-5V-5Mo-3Cr alloy offers a potential solution to thermomechanical processing challenges commonly associated with many commercially available beta and near-beta titanium alloys. Wrought process and heat treatment capabilities of the Ti-5553 alloy were investigated.  Forge processes and heat treatment conditions producing high strength conditions are identified and discussed. Those processes yielding an optimal balance of strength, ductility, and fracture toughness were selected for use on full-scale wrought Ti-5553 alloy components.  Wrought processing parameters and heat treatment will be reviewed and resulting mechanical properties will be presented with a focus on results of wrought processing of new high-strength, ultrasonic-friendly forging stock.
