Refining grain size to the nanocrystalline level has been suggested as a way of improving strength while enhancing ductility and toughness. However, there is a serious problem with production of fully-dense bulk nanostructured materials. Conventional methods of powder consolidation cannot be employed for nanophase materials, because they involve high temperature (at least 0.6Tm, Tm is the melting temperature) for extended times.
