Structural and physical properties of the high-entropy alloy ${(\mathrm{NbTa})}_{0.67}{(\mathrm{MoHfW})}_{0.33}$ were studied by x-ray powder diffraction, energy dispersive spectroscopy, magnetization, electrical resistivity, specific heat measurements. The experimental results supported theoretical calculations using two complementary approaches for electronic structure calculations: Korringa-Kohn-Rostoker method with coherent potential approximation (KKR-CPA) projector augmented wave (PAW)...
Th-containing superconducting high entropy system with the nominal composition (NbTa)[Formula: see text](MoWTh)[Formula: text] was synthesized. Its structural and physical properties were investigated by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, specific heat, resistivity magnetic measurements. Two main phases of alloy observed: major bcc structure minor fcc. The experimental results supported numerical simulation DFT Korringa-Kohn-Rostoker method...
A comparison of the results studies on influence structural defects critical parameters superconductivity has been made for high-entropy alloy (NbTa)0.67(MoHfW)0.33 and conventional superconducting magnet material Nb-47wt%Ti. Positron annihilation lifetime spectroscopy (PALS), electrical resistivity, magnetization magnetic susceptibility measurements were used. In addition, X-ray powder diffraction performed (NbTa)0.67(MoHfW)0.33. Due to rapid cooling materials after melting in arc furnace,...
