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…
Linear complexions directly modify dislocation motion in face-centered cubic alloys
Divya Singh, Vladyslav Turlo, Daniel S. Gianola +1
Linear complexions are defect phases that form in the presence of dislocations and thus are promising for the direct control of plasticity. In this study, atomistic simulations are…
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…
Grain incompatibility determines the local structure of amorphous grain boundary complexions
Pulkit Garg, Timothy J. Rupert
Amorphous grain boundary complexions lack long-range crystalline order but are not featureless, as distinct gradients in structural short-range order have been reported through the…
Intermetallic particle heterogeneity controls shear localization in high-strength nanostructured Al alloys
Tianjiao Lei, Esther C. Hessong, Jungho Shin +2
The mechanical behavior of two nanocrystalline Al alloys, Al-Mg-Y and Al-Fe-Y, is investigated with in-situ micropillar compression testing. Both alloys were strengthened by a hier…
