N2 - Irradiation response of cast (duplex) stainless steels were examined by atom probe tomography (CAES, Idaho). Non-aged and 10 000h at 400C aged samples were irradiated in Halden reactor to 0.08dpa. It was found that the neutron irradiation significantly increased spinoidal decomposition in the ferrite of the aged samples and increased the G-phase precipitate size. Most notably, the results indicate that neutron irradiation may accelerate the deterioration of ferrite in duplex steels at LWR relevant conditions.
