| Abstract Scope |
We present a study probing the local in bulk micro-mechanical fields at the chromium-zirconium interface of a new generation of coated nuclear fuel claddings designed for improved resistance to hypothetic accidental high temperature transients Light Water Reactors. The chromium is deposited by DC-MS and/or HiPIMS-PVD processes, which results in a complex polycrystalline microstructure, textured and with heterogeneous internal stress state. The scanning diffraction µLaue technique, available at the ESRF on beamline BM32, is able to discriminate contributions of each crystallographic phase and to reconstruct raster maps of the locally integrated orientation and strain fields for each grain along the depth. Furthermore, the DAXM variant allows to resolve the signal along this latter direction, leading to 3D maps down to sub-micron voxel resolution. These techniques give valuable insight on the mechanical state of complex interfaces, which is an important parameter to further rely on the coated materials mechanical behavior. |
