Prediction of Fracture Toughness of 2¼Cr-1Mo Pressure Steels from Charpy V-Notch Test Results

Source

The validity of the Barsom, Rolfe, and Novak correlation between Charpy energy, yield strength, and KIc in the upper-shelf region has been confirmed for 2¼Cr-1Mo pressure vessel steels. The relationship between the excess temperature and KIc/KIc-upper shelf has also been developed. Based on these relationships, KIc transition curves may be predicted from Charpy V-notch test results of 2¼Cr-1Mo pressure vessel steels.
