Temperature dependence of parameters characterizing different stages of the deformation consolidating is studied. Influencing of size of structural elements up to nanosizes on the termoaktyvation parameters of tension of flow, temperature dependence of fracture toughness is explored. Structural and temperature dependences of flow stress of the microlayered materials is studied The features of micromechanical behavior of coatings and thin films are explored. Approaches allowing estimating mechanical properties of these objects using the data obtained on systems film-substrate are developed. The characteristic sizes of structural elements are found, at which dependence of tension of flow on the size of grain changes. Conception of "useful" admixtures and alloying elements for creation of the superstrengthened nanocrystalline states is offered.
