The appearance of local misorientations in the interior of a crystal was described in terms of inhomogeneities in the dislocation structure. The evolution of the microstructure was considered to be a consequence of the interaction of a dislocation cell structure with dislocation fluxes of opposite sign and which contained differing mobile dislocation densities. By using this model, the formation of misorientations due to various causes could be predicted.
