Abstract We propose an experimental approach for investigation of the polycrystalline deformation behaviour at a grain scale. The technique is characterized by the joint application of micro material testing systems and the intragranular deformation analysis methods. It is attempting to map the deformation evolution at grain scale during the elastic and plastic deformations of polycrystalline specimens.
