| 英文摘要 | In order to analyze the irradiation-induced changes of ductile-to-brittle transition temperature (DBTT) of ferritic/martensitic (FM) steels, small punch (SP) tests were conducted on the specimens of Optifer-IX, Eurofer 97 and MA956 steels after irradiation in a target of the Swiss spallation neutron source (SINQ) at doses between 8.5 and 18.8 dpa and temperatures between 165 and 365 degrees C. The SP test results demonstrate that the DBTT of the three steels increases with irradiation dose, which is in agreement with the previous results of SP and Charpy impact tests on FM steels irradiated at SINQ Both SP and SEM observation results indicate that, among the three steels, Eurofer 97 possesses the highest resistance to irradiation-induced embrittlement. On the other hand, the ferritic ODS steel MA956 exhibits the poorest radiation resistance, manifested by the higher DBTT in both unirradiated and irradiated conditions and higher DBTT shift after irradiation as compared to Optifer-IX and Eurofer 97 steels.
