An estimate was made of the volume density of dislocation sources which were formed as a result of contact interaction between dislocations, gliding on an octahedral plane, and Lomer-Cottrell dislocation locks. The average distance between slip traces was estimated by assuming that, during deformation, each dislocation source formed a slip trace. This distance was found to be 2 to 3 orders of magnitude smaller than the experimentally observed value. It was concluded that dislocation lock sources could ensure the plastic deformation of face-centered cubic crystals.
