High-entropy alloys have been identified and manufactured that allow the deformation method to obtain nanostructured states. The characteristics of strength, ductility and nature of the destruction of this material in the nanostructured and recrystallized state in the range of 4.2 -1073 K. The influence of technological parameters of sputtering on the phase composition and physico-mechanical properties of nanostructured metal coatings from high-entropy alloys has been established. It was found that shear deformations at friction lead to the formation of thermally stable nanostructures in WPP with grain size within 30-70 nm and the depth of secondary structures at WPP friction reaches 40 nm The regularities of the change of the micromechanisms of strengthening during the transition from the micro- to the nanostructured state are established, and a theoretical description of the dependence of the structural sensitivity of the mechanical characteristics of high-etch alloys is proposed.
