Nano-lamellar materials with ultrahigh strengths and unusual physical properties are of technological importance for structural applications. However, these materials generally suffer from low tensile ductility, which severely limits their practical util

The possible optimization of strength and ductility in nanocrystalline and ultrafine grained metals is assessed. Most nanocrystalline metals show little ductility while exhibiting enhanced strength. The possibility that these properties can be optimized is discussed for microstructures with appropriate grain siz...
Both mechanisms are found to be of practical value in the solution of problems which involve increasing the strength of contact layers and resistance welds in various structures and optimizing regimes of plastic deformation and resistance welding. Criteria of contact strength are also presented for ...
Metals can be processed to reach ultra-high strength, but usually at a drastic loss of ductility. Here, we review recent advances in overcoming this tradeoff, by purposely deploying heterogeneous nanostructures in an otherwise single-phase metal. Several structural designs are being explored, ...
2024, Materials Science and Engineering: A Citation Excerpt : However, its application in industry is limited, mainly because of its poor ductility at low temperatures [4,5]. The poor ductility of magnesium (Mg) alloys is attributed to its limited non-basal slips, resulting in activating twinni...
Criteria of the contact strength, ductility, and fracture of materials in shear with bucklingA model is presented of the origination and suppression of the fracture of a contact surface during shear of its layers. The process is examined as a function of the configuration of projections on the ...
