Proc. ASME. PVP2023, Volume 5: Materials & Fabrication, V005T06A045, July 16–21, 2023
Publisher: American Society of Mechanical Engineers
Paper No: PVP2023-106094
... Abstract Four slabs cut out from a forging ring were normalized at 870°C, 885 °C, 900°C and 915°C for three hours. Cooling from normalizing to room temperature proceeded under forced air. Test specimens were extracted for Charpy impact testing at −46°C and metallographic examination...
