LX. The formation of immobile dislocations during slip

Abstract

Summary Lomer has pointed out that certain dislocations on intersecting slip planes in the face centred cubic lattice can join to form new dislocations. It is now proposed that these new dislocations dissociate into groups of imperfect dislocations which cannot move because of the arrangement of their associated stacking faults. These immobile dislocations may be important in work hardening.
