By electric spark dispersion were produced for the first time ultrafine powders (up to 5 µm) of high-entropy alloy (HEA) FeNiCoCrCu in various liquid media (ethanol, propanol, and water), and their effect on the phase composition and the ratio of the volume fractions of γ1 and γ2 phases was determined in comparison with this ratio in the original ingot. According to the analysis of the structure parameters and characteristics of the hyperfine magnetic interaction, as shown, the obtained powders inherit the phase composition of the cast alloy, but the formation of the b.c.c. phase, as well as simple and complex oxides after dispersion in ethanol and water, and dispersion in propanol also causes a change in the ratio γ1 і γ2 phases and the appearance of special carbides. The results are the basis for the development of a new method for obtaining highly dispersed and nanosized HEA powders. [ABSTRACT FROM AUTHOR] |
