An all-around way to analyze the corrosion behavior and the potential applications of high-entropy alloys coating

A Modern Approach to HEAs: From Structure to Properties and Potential Applications

“…where VEC > 8.6 indicates FCC and VEC < 6.87 indicates BCC. The synthesis of HEAs involves various techniques across solid, liquid, and gas states, each influencing the microstructure and properties of the alloys uniquely [6,[47][48][49][50][51][52][53][54][55]. Solidstate methods [56], such as mechanical alloying and spark plasma sintering, combine materials below their melting points, enhancing microstructure and element diffusion.…”

“…They examined a range of equiatomic alloys, studying their microstructures, hardness, and corrosion resistance [7,8]. Their findings expanded the understanding of HEAs, demonstrating their complexity and the influence of factors like atomic size difference, valence electron concentration, and electronegativity on their formation, as outlined by Hume-Rothery's rules [6].…”

“…High-entropy alloys (HEAs) have garnered significant attention in materials science due to their unique compositions and potential for exceptional mechanical properties [1][2][3][4][5]. These alloys, which consist of five or more elements in equal or nearly equal atomic ratios, were first conceptualized by Yeh et al in Taiwan in 1995, introducing a new class of materials distinguished by their simple solid-solution phases-face-centered cubic (FCC) and body-centered cubic (BCC)-and potential for intermetallic compound formation [6].…”

High-entropy-based nano-materials for sustainable environmental applications

“…10–12 Therefore, HEMs are experiencing increasing adoption in industrial, aerospace, and welding applications, as well as in the construction of heat exchangers and high-temperature furnaces. 13,14 Furthermore, within the realm of magnetism, HEMs containing magnetic ions have emerged as a versatile platform for tuning magnetic properties. Recent studies have demonstrated that the intricate interplay between local cationic disorder and the concentration of magnetic ions contributes to enhanced exchange coupling, making these materials conducive for applications in magnetic memory devices, magnetometers, and magneto-optical devices.…”
