Abstract

One of the main tasks of modern physical materials science is formulated to develop and study high-entropy alloys of the latest generation. A brief review of recent publications on promising areas of creation and application of high-entropy alloys is given. A set of high performance characteristics is identified for high-entropy alloys for use in modern science-intensive industries: wear resistance, strength and impact strength, chemical, radiation and corrosion resistance, low density, superplasticity and superconductivity, high and low thermal conductivity, diffusion resistance, low temperature coefficient resistance, environmental friendliness, etc. The areas of promising applications of high-entropy alloys in nuclear reactors, aerospace engines, gas and oil pipelines, offshore structures, computers and electronic devices are indicated. It is noted that many high-entropy alloys can be used in dual-use products. As examples, a proposal for the creation of thin-film highly resistive materials with a low temperature coefficient of resistance by the spinning method is considered. A tape made of a high-entropy Kantor alloy of non-equiatomic composition has been obtained and its properties have been studied. An assumption about the further development of high-entropy alloys has been made and substantiated.
