Query: Emergence of near-boundary segregation zones in face-centered cubic
  multi-principal element alloys   Grain boundaries have been shown to dramatically influence the behavior of
relatively simple materials such as monatomic metals and binary alloys. The
increased chemical complexity associated with multi-principal element alloys is
hypothesized to lead to new grain boundary phenomena. To explore the
relationship between grain boundary structure and chemistry in these materials,
hybrid molecular dynamics/Monte Carlo simulations of a faceted {\Sigma}11 <110>
tilt boundary, chosen to sample both high- and low-energy boundary
configurations, are performed in face-centered cubic CrFeCoNiCu and CrFeCoNi
equiatomic alloys. Unexpected enrichment of Fe is discovered in the
face-centered cubic regions adjacent to the interface and found to be
correlated with a structurally-distinct region of reduced atomic volume.
Comparison with the boundary of the same type in monatomic Cu demonstrates that
altered near-boundary regions exist in simpler systems as well, with the
chemical complexity of the multi-principal element alloys highlighting its
existence and importance.
