|On-Site Speaker (Planned)
The presentation will discuss recent research led and/or supported by University of Oxford using atom probe tomography (APT) to characterise the effects of exposure to the harsh reactor environment on material microstructure at the atomic-scale. APT is becoming an increasing critical role in the investigation of:
•the onset and evolution of neutron/ion irradiation induced solute clustering, the dissolution of secondary phase precipitates, segregation to grain boundaries and radiation induced dislocations;
•refining calibration of ion irradiation as a surrogate to investigate the effects of neutron irradiations;
•developing techniques utilising deuterium as a surrogate to investigate the embrittling effects of hydrogen pick-up and hydride formation;
•stress corrosion cracking.
Examples of advanced experiment and analysis techniques on a range of materials such as steels, zirconium and tungsten alloys, as well perspectives for further applications of APT to underpin nuclear research will be presented.
