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…
High-Entropy Grain Boundaries
Jian Luo, Naixie Zhou
Do high-entropy alloys and ceramics have their grain boundary (GB) counterparts? As the concept of high-entropy grain boundaries (HEGBs) was initially proposed in 2016, this articl…
Computing Grain Boundary 'Phase' Diagrams
Jian Luo
Grain boundaries (GBs) can be treated as two-dimensional (2-D) interfacial phases (also called 'complexions') that can undergo interfacial phase-like transitions. As bulk phase dia…
From High-Entropy Ceramics (HECs) to Compositionally Complex Ceramics (CCCs)
Jian Luo
This invited talk will review a series of our recent studies on high-entropy ceramics (HECs) and compositionally complex ceramics (CCCs) and discuss the future perspective. Various…
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…
21-Component Compositionally Complex Ceramics: Discovery of Ultrahigh-Entropy Weberite and Fergusonite Phases and a Pyrochlore-Weberite Transition
Mingde Qin, Heidy Vega, Dawei Zhang +4
Two new high-entropy ceramics (HECs) in the weberite and fergusonite structures, along with unexpected formation of ordered pyrochlore phases with ultrahigh-entropy compositions an…
