Scientific understanding of any kind of radiation effects starts from the primary damage, ie
the defects that are produced right after an initial atomic displacement event initiated by a …

Owing to their unique mechanical and functional properties, both amorphous and
nanocrystalline alloys have attracted extensive research interest over the past decades …

Abstract The combined Monte Carlo and Molecular Dynamics simulations were employed to
explore the influence of elemental segregation at grain boundaries (GBs) on the mechanical …

Current developments in kinetic and thermodynamic stabilization of grains in nanostructured
metals, alloys, and compounds are generalized and discussed in detail. As applied to the …

The breakdown from grain-size strengthening to softening mechanisms is generally well
understood for high-purity nanocrystalline materials when the mean grain size decreases to …

Nanocrystalline Cu–Ta alloys belong to an emerging class of immiscible materials with
potential for high-temperature applications. Differential scanning calorimetry (DSC), Vickers …

Grain boundary engineering is a versatile tool for strengthening materials by tuning the
composition and bonding structure at the interface of neighboring crystallites, and this …

Abstract Nanostructured Cu–Ta alloys have shown promise as high-strength nanocrystalline
materials in part due to their limited grain growth at high temperatures. In the present study …
