High-entropy alloys (HEAs), due to their exceptional mechanical properties, thermal stability, and corrosion resistance, have garnered significant attention in the field of materials science. This paper reviews primary preparation methods HEAs, such as carbothermal shock, electrochemical synthesis, spark plasma sintering, analyzes characteristics these terms compositional control synthesis efficiency. Through various characterization techniques, researchers can gain an in-depth understanding microstructure elemental distribution thereby enhancing performance applications catalysis. Although substantial progress has been made HEA research, challenges phase separation equipment costs continue hinder large-scale industrial applications. Future studies should focus on improving controllability environmental sustainability processes advance widespread application HEAs energy, catalysis, electronics.

Nanoporous structures with 3D interconnected networks are traditionally made by dealloying a binary precursor. Certain approaches for fabricating these materials have been applied to refractory multi-principal element alloys (RMPEAs), which can be suitable candidates high-temperature applications. In this study, nanoporous (np-RMPEAs) were fabricated from magnesium-based thin films (VMoNbTaMg) that had prepared magnetron sputtering. Vacuum thermal (VTD), involves sublimation of higher vapor pressure element, is novel technique synthesizing elements prone oxidation. When VMoNbTaMg was heated under vacuum, structure created the highest (Mg). X-ray photoelectron spectroscopy depth profiling indicated significantly less ligament oxidation during VTD as compared traditional methods. Furthermore, np-RMPEAs exhibited outstanding stability against coarsening, retaining smaller ligaments (~25 nm) at elevated temperature (700 °C) prolonged period (48 h).
