| Abstract Scope |
An in-situ annealing capability is being developed for integration with an existing in-situ mechanical testing system coupled with scanning electron microscopy and electron backscatter diffraction (SEM-EBSD) for the characterization of irradiated materials. The system will enable controlled-temperature annealing experiments with or without simultaneous mechanical loading, allowing direct observation of microstructural evolution during thermal treatment. Two sample holder configurations are being developed: one dedicated to annealing experiments and another supporting combined annealing and mechanical testing. The development required overcoming several technical challenges, including achieving uniform specimen heating, maintaining reliable thermal contact between the heater and specimen, and obtaining high-quality EBSD pattern at elevated temperatures. Pilot experiments using non-irradiated materials have been conducted to validate the heating design, temperature control, and EBSD performance before application to irradiated specimens. This capability will provide opportunities to investigate the temperature dependent evolution of radiation-induced defects and their influence on the mechanical behavior of irradiated materials. |
