GJB TC11 Heat Treatments

  • Heat treated: 940°C-960°C, insulation for 1h - 2h, air cooled; 520°C-540°C, insulation 6h, air cooled. It is allowed to adjust the first annealing temperature in the range of 30°C-50°C below transition temperature.
  • Heat treated: 950°C ± 10°C, insulation 1h, air cooling, followed by 530°C ± 10°C, insulation 6h, air cooling. The first annealing temperature is allowed to be below 30°C and 50°C below the phase point and is indicated in the measurement.
