A theoretical model which describes the generation of misfit dislocations in multilayered films deposited onto plastically deformed substrates with disclinations (defects of rotational type) was suggested. In the framework of the model, the ranges of the parameters (disclination strength, misfit parameters, layer thicknesses, characteristics of disclination arrangement) of a multilayered film/substrate composite for which the generation of misfit dislocations was energetically favourable were calculated. The specific features of the generation of misfit dislocations in multilayered films on disclinated substrates were analyzed with regard to a technologically interesting possibility for exploiting plastically deformed substrates.
