Abstract
In this paper, some of the older and newer Charpy-fracture toughness correlations have been examined and new correlations have been developed for predicting the ASTM E-1921 standard reference temperature, T0. The results have been applied to some selected new steels and compared with measured T0, where available. It is found that the predicted reference temperature from the new procedure gives reliable and acceptably conservative engineering estimate of T0. Predicted values of reference temperatures under dynamic conditions from these T0 using Wallin’s strain rate shift equation agree well with measured dynamic values for a few steels giving added support to the new procedure.
