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 …

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

Nanocrystalline (NC) metals suffer from an intrinsic thermal instability; their crystalline grains
undergo rapid coarsening during processing treatments or under service conditions. Grain …

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 …

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 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 …

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 …

Complexions are phase-like interfacial features that can influence a wide variety of
properties, but the ability to predict which material systems can sustain these features …
