Abstract
The surface tension energy of crystallites in polycrystalline materials having different microstructures and in nanomaterials has been estimated. A hypothesis is proposed, according to which the yield stress of materials is determined by the balance of elastic energy and the surface tension energy of crystallites. The independently measured value of surface energy can be used to estimate the yield stress of polycrystalline materials.
