  • Abstract
    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 observed is validated using reliable experimental results. The significance of some related observations is also discussed.
