Prospects for expanding the areas of HEAs application are noted.Ĭantor, B., Chang, I.T.H., Knight, P., and Vincent, A.J.B., Microstructural development in equiatomic multicomponent alloys, Mater. Examples of HEAs application as coatings for parts of watercrafts operating in sea water, dissimilar welded joints-parts of nuclear reactors-are given. ![]() High-entropy oxides of the (MgNiCoCuZn) 0.95Li 0.05O type with high dielectric properties in a wide frequency range can be used in electronic converters. Synthesized nanoporous AlCoCrFeNi HES have a high bulk density (up to 700 F/cm 3) and cyclic stability (>3000 cycles) and are used in supercapacitors. HEAs can be used as electrodes-anodes and cathodes for Li-ion and Na-ion batteries. The application fields of HEAs as catalysts for ammonia oxidation (PtPdRhRuCe), decomposition of ammonia (RuRhCoNiIr), oxidation of aromatic alcohols (Co 0.2Ni 0.2Cu 0.2Mg 0.2Zn 0.2), electrocatalysts for the evolution of hydrogen (Ni 20Fe 20Mo 10Cr 15CutPi, redox reactions (AlCuNiPtMn and AlNiCuPtPdAu), and methanol/ethanol oxidation are considered. By changing the stoichiometric composition of the CoCrFeNiTi HES, alloying them and conducting heat treatment, it is possible to obtain soft magnetic materials. The developed HEAs based on rare earth elements and metals of the Fe group of the YbTbDyAl Me type ( Me = Fe, Co, Ni) have a magnetocaloric effect, have the Curie point close to room temperature, and can be used in modern refrigeration devices. (MoTa) xNbTiZr products have successfully passed clinical trials when implanted in living muscle tissue. ![]() In biomedicine, protective coatings made of HEAs (TiZrNbHfTa)N and (TiZrNbHfTa)O possess biocompatibility, a high level of mechanical properties, high wear and corrosion resistance in physiological environments, and excellent adhesion. A brief review of the literature from the last five years on the analysis of using HEAs in specific knowledge-intensive industries is carried out. From the accumulated data on the structure, properties, stability, methods for obtaining high-entropy alloys (HEAs), created at the beginning of the 21st century, a whole range of useful properties were discovered, which allows for promising usages in various industries. ![]()
