Molecular Dynamics

Abstract:

This study used high-fidelity atomistic simulations with a machine-learning interatomic potential to examine creep deformation in MoNbTaW refractory high-entropy alloys under varying stress and temperature conditions. The results showed that larger grain size and the introduction of local chemical order both improve creep resistance by reducing grain-boundary-driven deformation and strengthening the microstructure for extreme-environment applications.
