The “Entropic Alloys and Meta-Metals” Section of Metals (ISSN: 2075-4701) highlights cutting-edge research on the design, synthesis, and applications of entropic alloys, amorphous alloys, and other advanced meta-metal systems. This Section embraces a multidisciplinary approach in order to advance understanding of the unique properties and behaviors of these materials, driven by high configurational entropy and complex atomic structures.

Key areas of interest include material design strategies, thermodynamic stability, structural and mechanical properties, corrosion resistance, and performance under extreme conditions. We also focus on the development of new processing techniques and computational modeling methods for designing innovative alloys with tailored properties for applications in industries.

We welcome both theoretical and experimental research, as well as applied studies that demonstrate industrial relevance and practical applications of entropic alloys and meta-metals. As all papers published in Metals are open access, readers enjoy free and unlimited access to all full texts. We encourage you to explore our highly cited papers from 2024–2025, listed below.
