Enhanced radiation damage tolerance of amorphous interphase and grain boundary complexions in Cu-Ta
Doruk Aksoy, Penghui Cao, Jason R. Trelewicz +2
Amorphous interfacial complexions are particularly resistant to radiation damage and have been primarily studied in alloys with good glass-forming ability, yet recent reports sugge…
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…
Maximum strength and dislocation patterning in multi-principal element alloys
Penghui Cao
Multi-principal element alloys (MPEAs), commonly termed as medium- or high-entropy alloys containing three or more components in high concentrations, render a tunable chemical shor…
Convolutional neural networks enable high-fidelity prediction of path-dependent diffusion barrier spectra in multi-principal element alloys
Zhao Fan, Bin Xing, Penghui Cao
The emergent multi-principal element alloys (MPEAs) provide a vast compositional space to search for novel materials for technological advances. However, how to efficiently identif…
Revealing hidden defects through stored energy measurements of radiation damage
Charles A. Hirst, Fredric Granberg, Boopathy Kombaiah +6
With full knowledge of a material's atomistic structure, it is possible to predict any macroscopic property of interest. In practice, this is hindered by limitations of the chosen…
Density functional theory calculation of edge stresses in monolayer MoS
Zenan Qi, Penghui Cao, Harold S. Park
We utilize density functional theory to calculate the edge energy and edge stress for monolayer MoS nanoribbons. In contrast to previous reports for graphene, for both armcha…
