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…
A Software Package for Generating Robust and Accurate Potentials using the Moment Tensor Potential Framework
Josiah Roberts, Biswas Rijal, Simon Divilov +6
We present the Plan for Robust and Accurate Potentials (PRAPs), a software package for training and using moment tensor potentials (MTPs) in concert with the Machine Learned Intera…
Machine Learned Interatomic Potentials for Ternary Carbides trained on the AFLOW Database
Josiah Roberts, Biswas Rijal, Simon Divilov +6
Large density functional theory (DFT) databases are a treasure trove of energies, forces and stresses that can be used to train machine learned interatomic potentials for atomistic…
A priori procedure to establish spinodal decomposition in alloys
Simon Divilov, Hagen Eckert, Cormac Toher +10
Spinodal decomposition can improve a number of essential properties in materials, especially hardness. Yet, the theoretical prediction of the onset of this phenomenon (e.g., temper…
Interfacial defect properties of high-entropy carbides: Stacking faults, Shockley partial dislocations, and a new Evans-Polanyi-Semenov relation
Samuel E. Daigle, Stefano Curtarolo, William G. Fahrenholtz +4
Using first principles calculations, {111} intrinsic stacking fault (ISF) energies in Group IVB, VB, and VIB high-entropy transition metal carbides are shown to be predictable from…
