| Abstract Scope |
This research investigates hydride formation and transformation mechanisms in Zircaloy-4 using a high-temperature X-ray diffraction (XRD) flow-through reactor capable of exposing metal tubes to inert or reactive atmospheres. Identical location electron backscatter diffraction (EBSD) and scanning electron microscopy (SEM) will observe the material's microstructure before and after XRD, targeting the same location. The study involves heating Zircaloy-4 with deuterium gas to understand hydride phase formation and transformation, focusing on metastable delta and gamma phases. By integrating EBSD-SEM with in operando XRD, we aim to elucidate microstructural changes, variations in partial pressure, and shifts in crystallographic orientations during hydride formation. These observations will provide critical insights into the mechanisms driving hydride formation and subsequent transformations. This work is central for a fundamental understanding of Zircaloy-4's behavior as a getter material in tritium-producing burnable absorber rods (TPBARs), contributing to the advancement of nuclear materials development. |
