Реферат: Formation of a MnFeCoNiCu high-entropy alloy by detonation spraying of a powder blend followed by laser treatment is reported for the first time. As the blend components differ by the deposition efficiencies, the composition of the deposited material may differ from the composition of the feedstock powder. In the coating formed from an equimolar mixture, the concentrations of iron and nickel are significantly higher than in the feedstock mixture. The composition of the feedstock powder is adjusted via decreasing the concentrations of nickel and iron to render the composition of the deposited layer close to the desired composition. A mixture containing 26Mn+11Fe+22Co+13Ni+28Cu (at.%) forms a Mn20Fe18Co22Ni18Cu22 coating. The laser treatment of the deposited layer allows for producing solid solutions of facecentred cubic structure. In the resolidified material, the interdendritic space is enriched by copper.
