Transmission electron microscopy was used to study the dislocation structure of monocrystals, with orientations of (001)[110], (110)[¯110] or (001)[100], after rolling to various degrees of reduction. It was found that crystals with the (001)[110] orientation could be deformed to extremely large (95%) degrees of reduction without losing their monocrystalline identity. Their structures were characterized by the presence of an homogeneous distribution of dislocations. Crystals with the other orientations began to develop a cellular structure after even small reductions. As the deformation approached 20 to 25%, these crystals were destroyed.
