Popis:	Thin (up to 100 µm) foils and coatings of high-entropy CrFeCoNiCux (x = 0...3.0) alloys (HEAs) were produced at different temperatures in the 525…1275 K range by electron-beam evaporation of ingots. It is shown that CrFeCoNiCux (where x > 0.3) condensates deposited at a temperature above 925 K have a dual-phase structure consisting of two FCC phases, while those deposited at a temperature below this value exhibit a single-FCC structure. It is also found that annealing of the deposited single-phase CrFeCoNiCux (x = 0.3…3.0) condensates at temperatures above 925 K results in the transition into a dual-FCC phase state. Yet, condensates with the copper content x
