Abstract Scope |
Oxide dispersion strengthened (ODS) alloys are promising candidate materials for the next generation advanced nuclear reactors due to their excellent resistance to irradiation damage and superior mechanical properties. Nevertheless, evaluating its performance especially after exposed to irradiation environment for a longer time/dose (higher dpa) is necessary. Ion irradiation is often selected to simulate neutron irradiation environment, especially to a higher dose (dpa). However, previous studies have shown different material response between ion and neutron irradiations. Therefore, efforts are needed to understand the differences between ion and neutron irradiations on ODS alloy.
In this study, MA956 ODS alloy that were neutron, ion and neutron+ion (combined) irradiated were analyzed using scanning transmission electron microscopy, atom probe tomography and nanoindentation techniques. Efforts are ongoing to understand the microstructure evolution and mechanical property changes in MA956 ODS alloys due to neutron and ion irradiations, and the results will be presented at the conference. |
