Structure, Stability, and Properties of High-Entropy Alloys
А. С. Рогачев
Abstract
Abstract—This critical review considers the fundamental concept, methods of obtaining, stability, and properties of a new class of materials—high-entropy alloys and compounds. An analysis of factors that determine the structure and stability of multicomponent disordered solid solutions has been carried out. Particular attention has been given to results obtained since 2017. The concept of temperature regions within stable and metastable phases, which explains the available experimental data, has been proposed.
