Abstract: In-situ mechanical testing during X-ray diffraction is performed on electro-deposited nanocrystalline Ni. It is found that the evolution of inter-granular stresses with plastic deformation is altered compared to what is usually found for coarse-grained metals. The results are rationalized by insights gained from molecular dynamics and quantized crystal plasticity modelling.
