原始语种摘要: Determination of the hyperfine-interaction parameters, acoustic and elastic properties of the high-entropy Al$_{x}$CuCrCoNiFe alloys (HEAs) ($x$ = 1, 1.8) in the as-cast state is carried out with the use of Mössbauer spectroscopy, x-ray diffractometry and high-precision ultrasonic techniques. Wide distributions of both the hyperfine-magnetic fields on iron nuclei (5.0–36.3 T) and the isomer shifts (-0.15–+0.28 mm/s) are detected in the HEAs that is result of multiphase state and inhomogeneous short-range order in the phases. As shown, the as-cast Al$_{x}$CuCrCoNiFe HEAs are acoustically and elastically inhomogeneous systems. Mean elastic moduli of the as-cast equimolar HEAs ($\langle E\rangle$ = 172.8 GPa, $\langle G\rangle$ = 65.3 GPa, $\langle B\rangle$ = 161.8 GPa) and the Debye...
