Abstract
It is shown that defects of rotation type form in polycrystals during the plastic deformation process at junctions and kinks of grain bounda ries. Their geometric properties are analysed and it is proved that in general these defects cannot be reduced to disclinations, but represe nt more complex linear-planar entities. The analysis shows that dipole s of defects of rotation type appear at ledges of boundaries. Such led ges are considered as dipole sources of the partial disclinations.
