Quasi-aperiodic grain boundary phases of Σ5 tilt grain boundaries in refractory metals
Enze Chen, Timofey Frolov
We report new ground-state structures and phase transitions in 5[001] tilt grain boundaries (GBs) in body-centered cubic (BCC) refractory metals Nb, Ta, Mo, and W. 5 tilt G…

Topological grain boundary segregation transitions
Vivek Devulapalli, Enze Chen, Tobias Brink +2
Engineering structure of grain boundaries (GBs) by solute segregation is a promising strategy to tailor the properties of polycrystalline materials. Theoretically it has been sugge…
