Abstract Scope |
In order to investigate the influence of defect sinks on the stability of the microstructure of a Fe-14Cr-1W-0.3Mn-0.2Ni-0.3Si alloy under irradiation, this alloy was studied in hot-extruded state (coarse grain (CG) alloy), after severe plastic deformation, resulting in grains of about 100nm (ultra fine grain (UFG) alloy) and after hot extrusion of the master alloy reinforced by nano-oxides (ODS alloy). CG and ODS alloys were elaborated at CEA Saclay. The UFG alloy was obtained by high pressure torsion (HPT) at USATU in Ufa. The 3 alloys were ion irradiated at 400°C in JANNUS facilities. Their microstructures were characterized by atom probe tomography in order to quantify Cr precipitation, Mn, Ni and Si clustering and to evaluate the stability of the nano-oxides in the case of the ODS alloy. |
