| Abstract Scope |
Synchrotron high-energy x-rays provide powerful tools for investigating dynamic behavior of nuclear materials under mechanical stress and elevated temperatures. This presentation highlights recent research at the 1-ID beamline of the Advanced Photon Source, showcasing advanced x-ray scattering and imaging techniques. Case studies include in-situ and 3D measurements that reveal neutron irradiation effects on deformation of structural alloys, and the kinetics of dislocation recovery in additively manufactured steels. Additionally, a novel framework integrating near-real-time crystal plasticity finite element modeling with in-situ experiments will be introduced. This approach, with its initial application in exploring deformation anisotropy in neutron-irradiated stainless steels, demonstrates the potential for predictive modeling to guide experiments with critical decision-making. The presentation will also feature the Activated Materials Laboratory, a new partner of the Nuclear Science User Facilities, which expands opportunities for synchrotron-based studies of activated materials. These advancements underscore the transformative impact of synchrotron techniques in nuclear materials research. |
