    Abstract

    A quantitative analysis of the evolution of the dislocation cell substructure during the deformation of face-centred cubic metals and alloys is presented. Particular features are distinguished in the behavior of pure metals and solid solutions with different states of atomic order. The influence of temperature and grain size on the main substructural parameters is studied. It is established that the dependence of cell size on dislocation density becomes less pronounced when going from single crystals to polycrystals with large and small grain sizes. An increase in deformation temperature is shown to have the same effect. The relationship between cell size and the width of cell walls is also examined.
