The partial dislocation model for the deformation mechanism of nanocrystalline materials is extended to consider the influence of non-uniform dislocation extension The non-uniform partial dislocation extension model is more consistent with experimental data than the original partial dislocation model. Additionally, the flow stress obtained from the non-uniform extension model is compared with that from the Hall-Petch relation (C) 2009 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
