    Abstract

    The dislocation substructure of f. c. c. alloys based on nickel, copper and palladium was studied by the method of transmission diffraction electron microscopy. As a result, types of dislocation substructures observed at different stages of deformation were revealed. The relations between the stages of stress-strain curves and types of dislocation substructure were determined. It has been established that each curve is connected with the appearance and the development of a definite type of the dislocation substructure. The transition from stage to stage, that is the ending of one and the beginning of another stage coincides with filling the volume of the crystal with one type of dislocation substructure and developing another. The formation of the substructure occurs when a certain magnitude of dislocation density is obtained in the crystal.
