About this Research Topic
As one of the hottest topics in materials science, both advanced amorphous and high-entropy alloys offer a unique suite of mechanical, physical, and chemical properties due to their unique structures. Being different from conventional materials, these alloys usually possess complex, multicomponent chemical compositions, and display chemically disordered structures. Due to the high mixing entropy effect, a simple supersaturated solid-solution phase tends to form for high-entropy alloys. In fact, amorphous alloys are also approximatively considered as supersaturated solid-solution solids even though the atomic structure of amorphous alloys is topologically disordered. Furthermore, from the point of view of thermodynamics, the formation of both advanced amorphous alloys and high-entropy alloys strongly depends on the entropy of mixing, the enthalpy of mixing entropy, or electronegativity. Therefore, in the current field of materials science, much attention has been paid to new alloy design, fabrication technique, microstructure modulation, and resulting properties for both advanced amorphous alloys and high-entropy alloys. Until now, some fundamental issues that challenge the proposed theories, models, methods, deformation mechanisms for conventional alloys also emerge with the development of both advanced metallic alloys.
The goal of this Research Topic is to collect articles mainly concerning the frontiers of research in amorphous and high-entropy alloys. Both experimental and theoretical approaches are encouraged, and review articles are also welcome. Some of the potential topics to be covered in this topic are as follows:
• Bulk alloys, thin films, and coatings;

• Phase transformations;
• Heat treatments and annealing;
• Severe plastic deformation;
• Microstructural evolutions and characterization;
• Physical and chemical property;
• Mechanical property.
