Abstract Scope |
Austenitic Stainless Steels (ASSs) are foreseen as cladding material for next generation reactors even though their swelling under irradiation will limit the fuel burnup. Solute elements, such as titanium and carbon, efficiently reduce this swelling but the mechanism is still unexplained.
Here we focus on the effect of an addition of titanium and carbon on the microstructure evolution of nickel at small irradiation dose. Nickel is considered as a model alloy for ASSs (same crystallographic structure). Ni alloys (Ni, Ni-Ti, Ni-Ti-C) were irradiated at 510°C in a TEM using the JANNuS-Orsay facility up to 0,06 dpa. The microstructure evolution of samples was recorded and analyzed. Results will be presented in details and discussed during the presentation. For example, we will describe the microstructure evolution (dislocation loop growth) in the three samples and compare the effect of an addition of titanium alone with that of titanium coupled to carbon. |
