B.S. TA 49 Heat Treatments


  • Solution treated + precipitation treated + centreless ground or machined; & = (900 +/- 10)°C / t = 1h per 25 mm ( >= 20 min) / AC + & = (500 +/- 5)°C / t = 24h / AC
  • The material and test samples shall be heat treated as follows:
    1) Heat at a temperature of 900°C ± 10°C and hold for 1h per 25 mm of section, with a minimum of 20 min
    2) Cool in air
    3) Heat at a temperature of 500°C ± 5°C and hold for 24h
    4) Cool in air
