摘要：
The objective of this work is to examine the susceptibility to hardening and embrittlement of Fe7.5/11CrWTaV reduced-activation (RA) and conventional 9/12Cr-Mo martensitic steels as a function of fluence up to 10 dpa and irradiation temperature in the range of 250-450 degreesC. For this purpose, materials were irradiated in the Osiris Reactor (Saclay) at 325 degreesC for Various doses ranging from 0.8 dpa to a maximum dose of 8-9 dpa. Available data concern the evolution of tensile properties for doses from 0.8 to 3.4 dpa. On the other hand, RA-steels were irradiated as Charpy V and tensile specimens in the high flux reactor (HFR) at Petten at temperatures ranging from 250 degreesC to 450 degreesC with a dose of about 2.4 dpa.
