Alloy 718Plus™ provides cost, manufacturing, and field service advantages relative to established cast plus wrought superalloy Waspaloy. Achieving the key characteristics needed to successfully replace an established production alloy in gas turbine applications requires an understanding of process variables on the microstructure and mechanical properties. Under a USAF Materials Affordability Initiative contract, a controlled experiment was performed on full-scale forgings to determine the influence of solution temperature, quench rate, and age temperature on microstructure, tensile and combination smooth-notch rupture behavior. The application-integrated project team consisting of engine manufacturers: GE, Honeywell, and Pratt & Whitney; forging suppliers Firth-Rixson and Ladish Company; primary metal producers Allvac and Carpenter Technology; in combination with the Air Force Research Laboratory Materials and Manufacturing Directorate, selected the Allvac-developed 718Plus™ alloy chemistry for scale-up and validation. Results are provided relative to anticipated AMS specification property limits.
