A model of cross-slip in a dislocation procession is discussed. The model is based on observations of dislocation arrays produced in neutron irradiated copper by a combination of cross-slip and secondary slip. The stresses of the arrays are modelled as those of an array of prismatic dislocations. an
Plastic deformation by slip induces rotations of the crystallographic lattice and evolution of dislocation structures. Both lattice rotations and dislocation structures exhibit a dependence on the grain orientation, which reflects underlying relations to the slip pattern. Relations between the type
