Multi-scale Investigation of Chemical Short-Range Order and Dislocation Glide in the MoNbTi and TaNbTi Refractory Multi-Principal Element Alloys
Hui Zheng, Lauren T. W. Fey, Xiang-Guo Li +6
Refractory multi-principal element alloys (RMPEAs) are promising materials for high-temperature structural applications. Here, we investigate the role of chemical short-range order…
A Universal Machine Learning Model for Elemental Grain Boundary Energies
Weike Ye, Hui Zheng, Chi Chen +1
The grain boundary (GB) energy has a profound influence on the grain growth and properties of polycrystalline metals. Here, we show that the energy of a GB, normalized by the bulk…
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…
Complex Strengthening Mechanisms in the NbMoTaW Multi-Principal Element Alloy
Xiang-Guo Li, Chi Chen, Hui Zheng +2
Refractory multi-principal element alloys (MPEAs) have exceptional mechanical properties, including high strength-to-weight ratio and fracture toughness, at high temperatures. Here…
Grain Boundary Properties of Elemental Metals
Hui Zheng, Xiang-Guo Li, Richard Tran +5
The structure and energy of grain boundaries (GBs) are essential for predicting the properties of polycrystalline materials. In this work, we use high-throughput density functional…
