Relationships between load-time and load-deflection curves during impact in Charpy impact test have been simultaneously observed on a reactor pressure vessel steel plate, a low carbon Al-killed grain-refined steel. A precision wire wound variable resistance is used for deflection detecting element, and satisfactory result on the resolution of deflection is obtained. Observed load-deflection curves are similar to load-time curves at each testing temperature. Absorved energy from area under the load-deflection curve is rather smaller than the one from indicator of tester. The result that the time axis of the load-time curves can convert linearly to the deflection axis is obtained from analysis of deflection-time curves which are composed of both curves.
