Machine-Learning Assisted Atomic Simulations of Defect Dynamics in Multicomponent Concentrated Alloys
… predict vacancy migration barriers across a wide compositional range. Due to the challenges of exploring the vast HEA compositional space, to date most experimental and computational studies have been limited to equiatomic compositions. This model, remarkably effective despite being trained solely …
