资源简介：

This proposal aims at investigating the 3D damage evolution during first stage fatigue near a penetrable grain boundary with pre-defined transmission path in micron-sized copper cantilevers. To do so, we will combine the recent 3D-microLaue technique of BM32 with the users’ in situ micro-deformation capabilities (MA-3607), to measure cyclically loaded Cu bi-crystals. The X-ray microscope will provide 3D microstructural quantities (local strains, dislocations densities, etc.) with high spatial resolution (< 0.5 µm) relevant to understand the interaction mechanisms between dislocations and grain boundaries, which will help formulating mechanism-based material laws.
