This investigation describes the changes in the phase’s micromechanical properties as a result of alloying elements moving at interdiffusion. The induction of the interdiffusion between different phases of a Ni-based single crystal superalloy still is a challenging issue in this field of the materials science. For this we used novel technique - hard cyclic viscoplastic deformation at room temperature. The chemical compositions of the phases were determined by the cumulative bulk deformation. For detailed knowledge of this material behavior during life time the micromechanical properties of phases were investigated by nanoindentation and the results were analyzed by scanning electron microscope and the corresponding chemical content was investigated by X-ray microanalysis.

Multilayer films of two types, namely, films with alternating nanolayers Ag 2 S and AgI and alternating nanolayers Ag 3 SI and AgI, are prepared by laser ablation. The conductivity of the film samples is investigated using impedance spectroscopy. The ends of fractures of the multilayer films are examined with electron microscopy.
