摘要
In order to identify the various contributions to the radiation damage of RPV steels, we performed a comparative analysis of a set of our experiments. They were carried out on three ferritic Fe-Cu alloys irradiated at 290 degrees C with electrons or neutrons. The evolution of the mechanical properties has been characterized by Vickers (4.9 N) hardness and the microstructure has been studied by small angle neutron scattering (SANS), Atom Probe (AP) and Positron Annihilation. We have identified three irradiation-induced features which can harden low copper ferritic model alloys: point-defect clusters and copper-rich clusters, produced by displacement cascades, as well as copper-vacancy(ies) complexes, induced by isolated vacancies.
