Abstract
- 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, T 0. The results have been applied to some selected new steels and compared with measured T 0, where available. It is found that the predicted reference temperature from the new procedure gives reliable and acceptably conservative engineering estimate of T 0. Predicted values of reference temperatures under dynamic conditions from these T 0 using Wallin’s strain rate shift equation agree well with measured dynamic values for a few steels giving added support to the new procedure.
