Definitions

  • the billet is then forged using known techniques, such as those currently utilized to produce Alloy 706 and Alloy 718 rotor forgings for large industrial turbines, but modified to take advantage of fine grain billet techniques.
  • Forging is performed at temperatures and loading conditions that allow complete filling of the finish forging die cavity, avoid fracture, and produce or retain a fine uniform grain size within the material of not larger than ASTM 8.
  • ASTM 8 ASTM 8
  • An illustrative example of an appropriate heat treatment process for the Alloy 725 entails a solution heat treatment at a temperature of about 900 °C (about 1650 °F) for approximately four hours, followed by two step aging at a temperature of about 760 °C (about 1400 °F) for approximately eight hours, then cooling at a rate of 56 °C (about 100 °F) per minute to about 620 °C (about 1150 °F) and holding for approximately eight hours, followed by air cooling.
