A homogeneous dislocation distribution in deformed metals is unstable with respect to clustering of dislocation dipoles. The main reason for formation of the dislocation clusters is a net dipole drift to stress concentrations created by glide dislocations in a applied stress state. Linear stability analysis indicates that the suggested model gives a reasonable description of the most important features of the early stage of dislocation structure development as observed in metal crystals in single slip under both unidirectional and cyclic deformation.La distribution homogène des dislocations dans les métaux déformés ne reste pas stable à cause de l'agglomération des dipoles de dislocations. La formation des amas de dislocations peut être exp...
