Studies involving the application of the instrumented Charpy impact test are presented. The studies were concerned with the effect of strain rate, alloying, and irradiation on the ductile-brittle transition temperature (DBTT) and fracture behavior of pressure vessel steels. The effect of strain rate on a 0.02C and 0.02C-3.5Ni steel was evaluated by comparing instrumented Charpy tests with three-point slow bend tests on Charpy V-notch specimens. Increasing the strain rate increased the DBTT, increased the yield stress, and decreased the temperature dependence of the yield stress. The strain rate sensitivity of the yield stress was mainly responsible for the increase in the DBTT.
