Grain size has a profound effect on the mechanical response of metals. Molecular dynamics
continues to expand its range from a handful of atoms to grain sizes up to 50 nm, albeit …

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 wider application of copper alloys is challenged due to their relatively low strength and
thermal stability. Here we report a nano-reinforcement dispersion strategy to achieved an …

Structural transformations at interfaces are of profound fundamental interest as complex
examples of phase transitions in low-dimensional systems. Despite decades of extensive …

New classes of reactive systems that are characterized by nano-scale heterogeneity and
possess extremely high reactivity, as compared to that for similar reactive systems with micro …

Solute segregation at grain boundaries (GBs) is a key mechanism to stabilize
nanocrystalline alloys. To date, the standard approach to design and screen for …

Dispersion-strengthened copper alloys can achieve ultra-high strength, but usually at the
expense of ductility. In this study, a strategy for overcoming strength-ductility tradeoff of Cu …

Mitigating grain growth at high temperatures in binary nanocrystalline alloys is important for
processing nanocrystalline alloy systems. The objective of this research is to develop a …

The interaction of alloying elements with grain boundaries (GBs) influences many
phenomena, such as microstructural evolution and transport. While GB solute segregation …

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 …
