Single crystals were deformed cyclically to saturation in single slip at room temperature. The microstructure consisted of dense dipole bundles which were separated by channels having a low dislocation density. The dipole height in the pre-saturation microstructure was almost independent of location; it was equal in the dipole bundles and within the channels, for both primary and secondary dipoles. The results suggested the existence of an homogeneous stress distribution without internal stresses.
