The segregation of solute atoms at grain boundaries (GBs) can profoundly impact the
structural properties of metallic alloys, and induce effects that range from strengthening to …

Mg grain boundary (GB) segregation and GB diffusion can impact the processing and
properties of Al-Mg alloys. Yet, Mg GB diffusion in Al has not been measured experimentally …

A set of modified embedded-atom method (MEAM) potentials for the interactions between Al,
Si, Mg, Cu, and Fe was developed from a combination of each element's MEAM potential in …

Solute segregation at grain boundaries (GBs) is emerging as an alloy design tool, uses of
which include the stabilization of nanocrystalline alloys. To predict the equilibrium …

We found that when Mg is added to Al in small amounts, it results in alloys that exhibit both
significantly higher strength and ductility than those of the pure Al counterpart. Strength and …

In-spite of all of the unique properties of nanocrystalline materials, they are notorious when it
comes to their susceptibility to thermally induced grain coarsening, thus imposing an upper …

Even minute amounts of one solute atom per one million bulk atoms may give rise to
qualitative changes in the mechanical response and fracture resistance of modern structural …

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

Solute segregation at grain boundaries (GBs) is known to have a profound impact on
material properties, and as such is becoming routinely used as an element in alloy design …

Various industrial/commercial applications use Al-Mg alloys, yet the Mg added to Al
materials, to improve strength, is susceptible to surface segregation and oxidation, leaving …
