Frustrated metastable-to-equilibrium grain boundary structural transition in NbMoTaW due to segregation and chemical complexity
Ian Geiger, Diran Apelian, Xiaoqing Pan +3
Grain boundary structural transitions can lead to significant changes in the properties and performance of materials. In multi-principal element alloys, understanding these transit…
Influence of chemistry and structure on interfacial segregation in NbMoTaW with high-throughput atomistic simulations
Ian Geiger, Jian Luo, Enrique J. Lavernia +3
Refractory multi-principal element alloys exhibiting promising mechanical properties such as excellent strength retention at elevated temperatures have been attracting increasing a…
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…
