Atomic Representations of Local and Global Chemistry in Complex Alloys

Megan J. McCarthy, Jacob Startt, Rémi Dingreville +2

The exceptional properties observed in complex concentrated alloys (CCAs) arise from the interplay between crystalline order and chemical disorder at the atomic scale, complicating…

Elasticity of spheres with buckled surfaces

Yingzhen Tian, Megan McCarthy, Megan King +1

The buckling instabilities of core-shell systems, comprising an interior elastic sphere, attached to an exterior shell, have been proposed to underlie myriad biological morphologie…

Chemical order transitions within extended interfacial segregation zones in NbMoTaW

Doruk Aksoy, Megan J. McCarthy, Ian Geiger +6

Interfacial segregation and chemical short-range ordering influence the behavior of grain boundaries in complex concentrated alloys. In this study, we use atomistic modeling of a N…

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…
