Emergence of near-boundary segregation zones in face-centered cubic multi-principal element alloys
Megan J. McCarthy, Hui Zheng, Diran Apelian +6
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…
Alloying induces directionally-dependent mobility and alters migration mechanisms of faceted grain boundaries
Megan J. McCarthy, Timothy J. Rupert
Faceted grain boundaries exhibit unusual segregation and migration tendencies. To gain a deeper understanding of how solute atoms interact with faceted interfacial structures durin…
Shuffling mode competition leads to directionally-anisotropic mobility of faceted Σ11 boundaries in face centered cubic metals
Megan J. McCarthy, Timothy J. Rupert
Faceted grain boundaries can migrate in interesting and unexpected ways. For example, faceted Σ11 <110> tilt grain boundaries were observed to exhibit mobility values that could be…
Emergence of directionally-anisotropic mobility in a faceted 11 <110> tilt grain boundary in Cu
Megan J. McCarthy, Timothy J. Rupert
Faceted grain boundaries, where grain boundary area is increased in the name of producing low-energy segments, can exhibit new and unexpected migration trends. For example, several…
