Films of high entropy alloys. A review

A brief review of research publications on films and coatings made of high-entropy alloys and solid solutions of their simple compounds is presented. A new approach to developing these materials is based on mixing five or more basic elements of the Periodic Table in equimolar or similar ratios. These materials are characterized by a high configurational entropy of mixing. As a result, during crystallization, these materials tend to form solely simple solid solution phases, mainly with a cubic crystal structure (face-centered – FCC and body-centered – BCC). This review is aimed at forming a general understanding of this new direction of materials science, which opens up unlimited prospects in the search for materials with ultra-high mechanical, thermal, corrosion, and other useful properties.
