Electron tailoring of thermal and magnetocaloric properties in Tb55TM17.5Al27.5 (TM = Fe, Co, and Ni) metallic glasses
Published 2024-11-01“…It is found that with the decrease of the weighted 3d electron number of TM elements, the thermal stability of rare-earth-base MGs is effectively enhanced ascribed to the strong f - d orbital hybridization effect, along with the enhanced 3d - 3d exchange interaction that induces a high Tc. …”

Numerical study for the effect of angle between inner wall of Wehnelt electrode and its axis on beam dynamics in a thermionic electron gun
Published 2025-01-01“…The results indicate that a change in α causes a variation in the potential on the axis and its first and second derivatives to the axial distance, which in turn causes changes in the beam current and emittance and the radius and position of the beam waist; however, it has no significant effect on the kinetic energy of the electrons. When 75° < α ≤ 90°, the beam cannot be focused effectively. …”

Overvoltage Protection for High Frequency High Voltage Power Transformers
Published 2019-12-01“… Transformers with high-voltage operation may have undesired behavior due to the effects of their parasitic elements. In power electronics applications, if the primary voltage has harmonics, transformer resonances may be excited, causing high primary currents and secondary voltage stress, compromising the device isolation. …”

Formation mechanism of W phase and its effects on the mechanical properties of Mg−Dy−Zn alloys
Published 2025-05-01“…The morphology and dimension of W phases play an important role in determining mechanical properties of Mg−RE−Zn (where RE denotes rare earth elements) alloys. In this study, the γ′ platelet and W particle occurred in the aged Mg−2Dy–0.5Zn (at.%) alloys were investigated by aberration-corrected scanning transmission electron microscopy. …”

Effect of Mn element on the microstructure and wear resistance of hypereutectic Al-22Si-2Fe-xMn alloys produced by inclined cooling
Published 2017-02-01“…It is shown that inclined cooling preparation technology can improve the morphology and size of primary Si, but has limited effect on the needle-shaped Fe-rich phase. The effect of Mn addition on the crystal structure of Fe-rich phase under the condition of inclined cooling was analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM). …”
