Реферат: This investigation focuses on the structural characteristics of AlFeCoNiCu high-entropy alloys (HEAs) fabricated using two approaches. The alloys were obtained by the spark plasma sintering (SPS) or hot pressing (HP) treatment of layers deposited by detonation spraying of a mixture of the elemental powders. The feedstock powder mixture used for the spraying was also directly consolidated by SPS under the same conditions (without any pre-alloying treatment). The goal of this work was to conduct a comparative analysis of the compositional and structural features of AlFeCoNiCu HEAs formed by different methods. The SPS treated deposited layer showed a more uniform structure and composition than the alloy obtained directly by SPS of the powder mixture. All alloys processed by SPS or HP were face-centered cubic solid solutions. The alloys obtained from the deposited precursors showed deviations from the nominal composition of the powder mixture. However, the compositional differences and nonuniformities did not affect the hardness of the alloys or the influences of these factors compensated each other.. This work shows that, for practical applications, thick samples of AlFeCoNiCu can be produced by SPS of the elemental powder mixtures, while for thin layers and coatings detonation spraying followed by SPS/HP can be applied.
