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 ultr...

摘要:The structure of condensates and cast samples of aluminium, Al–Fe and Al–Zr alloys crystallized from both the melt and the vapour phase in a vacuum is studied. As shown, the alloying of the vapour flow of a matrix metal, i.e. aluminium, with iron up to $\cong$ 3 at.% reduces...

摘要:Magnetic properties of the 3$d$(Fe)–4$f$(RE) intermetallides are calculated by introduction of both the many-electron operator spinors (MEOS) and the chemical-bonds’ fluctuations as MEOS Fourier images. Dependences of both the critical temperature $T_{\textrm{c}}$ and the co...

摘要:Short-range order in amorphous iron-based metal alloys is investigated by the EXAFS-spectroscopy method. According to EXAFS study, the increase of the content of Co atoms in the amorphous metal alloy (AMA) of Fe–Co–B system leads to decrease of the radius of first coordinati...
