Grain boundary segregations were investigated by atom probe tomography both in an ultrafine grain steel and in an aluminum alloy processed by severe plastic deformation. The unusually high solute concentrations that were measured are attributed to the “non-equilibrium” state of the boundaries. The mechanisms of these deformation induced segregations are discussed.
