Abstract

The effect of grain size and strain on the flow stress of polycrystals has long been studied. However, the effect especially for polycrystalline iron, still cannot be fully explained by most of the models. In this paper, a unified equation based on a one-parameter approach has been proposed to predict the relation between flow stress and grain size at various strains. The predictions are found to be consistent with the published experimental data.
