Defect Landscapeand Stability of High-Entropy Carbides
Abstract High-entropy carbides (HECs) can be stabilized as single-phase solid-solution microstructures by kinetically trapping a “high-entropy state” under ambient conditions; however, such microstructures may represent metastable states rather than true thermodynamic equilibrium...
