Abstract Scope |
Materials exposed to nuclear environments face the combined effect of radiation, temperature, corrosion, stress and time contributing to changes in microstructure resulting in materials property changes. Under neutron irradiation materials are activated, while under ion irradiation small volumes are irradiated. In either case it is advantageous to test small volume of materials fostering the need for small scale mechanical testing. Especially indentation-based testing allows for extensive statistics in a short period of time in a cost effective matter. However, the question remains how to relate the obtained nanoindentation data to properties relevant to the operation of the nuclear structure. This presentation features the state of the art of nanoindentation on irradiated materials and how one can obtain relevant bulk properties demonstrated on actual reactor retrieved materials and ion beam irradiated materials. |
