| Abstract Scope |
In order to get a better understanding and a more accurate anticipation of the neutron fluence dependence of the microstructure of reactor pressure vessel steels, it is important to determine unambiguously the nature of the irradiation induced features usually observed by APT (solute rich clusters, solutes-point defects complex clusters, thermodynamically stable phases….).
Post irradiation annealing can bring information about the stability and the nature of these features. In this work, a FeMnNi model alloy was neutron irradiated at a dose of 0.2dpa at 300°C. Post irradiations annealing during 30’ were performed at 400, 500 and 600°C.
In order to investigate the irradiated microstructure and the stability of irradiation induced features, materials were characterized by atom probe tomography. Results will be described and compared with positon annihilation data obtained on the same samples at SCK.CEN. |
