Grain-Size Dependence of Thermal and Electrical Properties in (Cr,Mo,Ta,V,W)C1-δ High-Entropy Carbide Ceramics
Ali Sarikhani, Gregory E. Hilmas, David W. Lipke +4
Thermal and electrical transport in high-entropy carbides can be influenced by grain-boundary scattering, but the relevant microstructural regime remains uncertain. Here, near-full…
The Case Against Hall-Petch Hardening in High Entropy Carbide Ceramics
Ali Sarikhani, Ana C. Feltrin, Gregory E. Hilmas +5
Grain size is often used with the Hall-Petch relationship to justify differences in hardness in ceramic materials. Herein, hardness does not vary systematically with grain-size for…
Grain-Boundary Premelting in High-Entropy Transition Metal Carbides
Marium M. Mou, Caleb Schenck, Samuel E. Daigle +4
Grain-boundary segregation and thermally induced interfacial disordering were investigated in four high-entropy transition metal carbides using Monte Carlo (MC) sampling and molecu…
The AFLOW Library of Crystallographic Prototypes: Part 5
Nicholas H. Anderson, Michael J. Mehl, Hagen Eckert +3
The AFLOW library of crystallographic prototypes has been updated to incorporate an additional 344 entries, which now reaches 2,127 prototypes. ICSD and CCDC numbers have been adde…
Grain Growth Kinetics in (Cr,Mo,Ta,V,W)C1-δ High-Entropy Carbide Ceramics
Ali Sarikhani, Gregory E. Hilmas, David W. Lipke +5
Understanding grain-boundary mobility during spark plasma sintering can enable microstructure control in high-entropy carbides, yet quantitative grain-growth kinetics remain scarce…
Disorder viscosity correction approach to calculate spinodal temperature and wavelength
Simon Divilov, Hagen Eckert, Nico Hotz +2
Spinodal decomposition, a key mechanism to microstructure formation in materials, has long posed challenges for predictive modeling, due to the need for parameter-free approaches t…

Variable-Temperature Plasmonic High-Entropy Carbides
Simon Divilov, Sean D. Griesemer, Robert C. Koennecker +9
Effective thermal management at variable and extreme temperatures face limitations for the development of novel energy and aerospace applications. Plasmonic approaches, shown to be…
Soliquidy: a descriptor for atomic geometrical confusion
Hagen Eckert, Sebastian A. Kube, Simon Divilov +10
Tailoring material properties often requires understanding the solidification process. Herein, we introduce the geometric descriptor Soliquidy, which numerically captures the Eucli…
The AFLOW Library of Crystallographic Prototypes: Part 4
Hagen Eckert, Simon Divilov, Michael J. Mehl +5
The AFLOW Library of Crystallographic Prototypes has been updated to include an additional 683 entries, which now reaches 1,783 prototypes. We have also made some changes to the pr…
Developments and applications of the OPTIMADE API for materials discovery, design, and data exchange
