A COMPARISON OF CHARPY V-NOTCH, DYNAMIC TEAR, AND PRECRACKED CHARPY IMPACT TRANSITION-TEMPERATURE CURVES FOR AAR GRADES OF CAST STEEL

Impact tests using Charpy V-notch, Dynamic Tear and Precracked Charpy samples were conducted on AAR-B, AAR-C (several compositions and heat treatments), and AAR-E cast grades of steel and on a high-strength, alloy cast steel. Graphical presentations of the transition-temperature data are given. Differences in the relative shapes of the curves and the locations of the NDT temperatures with respect to the transition temperatures are discussed. Fracture toughness, K sub Id, values are also presented.
