An inverse Hall-Petch effect has been observed for nanocrystalline materials by a large number of researchers. This effect implies that nanocrystalline materials get softer as grain size is reduced below a critical value. Postulated explanations for this behavior include dislocation-based models, di

A simplified procedure for an order of magnitude experimental validation of a recently proposed model for the strain-rate dependent deformation of nanostructured materials is given. The grain size dependence of hardness predicted by the model in the range where the inverse Hall-Petch effect is obser
We propose a composite model to explain the phenomena of strength softening with decreasing the grain size, which was reported in some nanocrystalline (nc) materials. We assume that a nc material consists of a grain interior and an amorphous grain-boundary layer. The grain interior deforms elastical
