The mechanism for the work hardening of superstructures proposed by Vidoz and Brown is modified. It is shown that this model explains the experimental results even when only a very small increase in the forest density, possibly too small to be observed experimentally, takes place during deformation. It is suggested that this small contribution of secondary slip may be due to a latent hardening effect. Analytical expressions for the stress to move primary and conjugate dislocation in a crystal are derived. The discussion shows that the antiphase boundary tube mechanism can explain most of the available experimental results.
