The multi-scale pattern composed of different scale patterns has been developed to measure the localized deformation for structure materials with complex microstructure. The measurement ofmultiscale deformation and strain distribution was investigated by in-situ FE-SEM observation. The measurement method was applied to investigate local deformation o f the hierarchical structure material. In-situ observation of the material subjected to tension was conducted to identify local deformation under various applied loading. Heterogeneous intrinsic grain-scale plastic defrmation was clearly observed and it increased with increasing macro-scale plastic deformation.
