Interlinking the mechanical properties of materials to their underlying and evolving microstructure is vital for a mechanism-based understanding of deformation, in particular at the micron scale. Numerous characterization tools, like SEM, TEM as well as synchrotron based Laue microdiffraction (μ Laue) offer a complementary toolbox being well suited to answer most questions in material science today. However, the current toolbox is either limited to surface information (e.g. SEM), thin samples (TEM) or integrated information (μ Laue). Also, the precision in determining the local strain tensor by the aforementioned techniques is, for most applications, insufficient.
To close this gap, we have combined a DAXM setup with a nanoindenter at BM32 of the European Synchrotron (ESRF). Subsequently, we applied this new instrument to understand the deformation behaviour of 5Ám sized bi-crystalline cantilevers by analysing the storage of dislocation in 3D and the local deviatoric (elastic) strain distribution.
