PROPRIETARY ATI Ti17 Heat Treatments

  • There are different solution heat treatments for alpha-beta and beta processed material. Alpha-beta processed material has a double solution treatment; the first treatment is at 1500 to 1575°F (815 to 860°C) for 4 hours followed by rapid air cooling. The higher temperatures are used when higher toughness is desired. The second solution treatment is done at 1475°F (800°C) followed by a water quench. Fan air-cooling may be used for thinner sections; however, higher and more consistent properties may be obtained by water quenching. Beta processed material receives a single solution anneal at 1475°F (800°C) for 4 hours. The recommended aging treatment for both alpha-beta and beta processed materials is 1150 to 1200°F (620 to 650°C) for 8 hours.
