WebNext example. During polygonization (recovery of a cold-worked crystal), dislocations of the same sign arrange into a low energy configuration the low angle grain boundary (LAGB). In this case a new defect, the LAGB has been created. Also, the statically stored dislocations (present randomly in the crystal) have become structural dislocations.
