摘要：

The effectiveness of mini-size Charpy V-notch specimens with a 1.5 or 1.0 mm square cross section in measuring the ductile brittle transition temperature (DBTT) and upper shelf energy (USE) compared with full-size specimens is evaluated for a ferritic steel. It is shown that the data from the mini-size specimens can be used to estimate the DBTT and USE for full-size specimens when the measured absorbed energy-temperature curves are normalized by appropriate parameters. The result is applied to the study of neutron irradiation embrittlement of low-activation ferritic steels.
