The regularities of dislocation storage during the deformation of homogeneous polycrystalline solid solutions with different degrees of solid-solution hardening have been studied and described. The effect of alloy concentration and test temperature is considered. The role of different dislocation density components (average scalar dislocation density, excess density, and dislocation density in walls and cells) is selected. Particular attention has been paid to the parameters of cellular substructure measured at different test temperatures and alloying concentrations. The important role of the solid-solution hardening in the regularities of dislocation storage is established.
