Abstract
The structure and phase composition of an ultrafine-grained aluminum alloy subjected to tension under superplasticity conditions are studied. It is shown that phase transformations governed by solid solution decomposition occur in the surface layer. The rate of these phase transformations in the near-surface layer is higher due to intensive grain boundary sliding. Maximum changes of the structural-phase state of the alloy are observed in a near-surface layer of about 10 μm thick.
