Full text not available from this repository.
This article briefly summarizes the extensive information now available, from recent experiments and theoretical models, addressing the enhanced tensile ductility of nanocrystalline (NC) and ultrafine-grained (UFG) metals. Special attention is devoted to the key strategies and procedures developed to concurrently optimize both the strength and tensile ductility of NC and UFG metals with an emphasis on the effects of basic deformation mechanisms, crystallographic structure, chemical composition and the presence of second-phase precipitates.
