Abstract The multicomponent films of Al-Co-Cr-Fe-Mn-Ni-Si-V high-entropy alloys obtained by splat-quenching from melt were investigated. Phase formation criteria for high-entropy alloys were considered. The films have a structure with body-centered cubic lattice. The value of lattice parameters of the investigated alloys suggests that the solid solutions are form on the base of Cr lattice, in view of its higher melting temperature. The positive influence of microstrains level and dislocation density on the microhardness values of splat-quenched high-entropy alloys has been established. Improved mechanical characteristics are ensured by the strong distortion of the crystal lattice due to the differences in atomic radii of the elements.
