Designing for Cooperative Grain Boundary Segregation in Multicomponent Alloys
Malik Wagih, Yannick Naunheim, Tianjiao Lei +1
Tailoring the nanoscale distribution of chemical species at grain boundaries is a powerful method to dramatically influence the properties of polycrystalline materials. However, cl…

Grain Boundary Segregation Predicted by Quantum-Accurate Segregation Spectra but not by Classical Models
Malik Wagih, Yannick Naunheim, Tianjiao Lei +1
In alloys, solute segregation at grain boundaries is classically attributed to three driving forces: a high solution enthalpy, a high size mismatch, and a high difference in interf…
