Special Issue Information
Dear Colleagues,
High-entropy alloys (HEAs), characterized by their multi-principal element compositions, have introduced a new paradigm in alloy design by departing from traditional base element concepts. Their unique chemical complexity enables the formation of simple solid solution phases, sluggish diffusion, and highly tunable microstructures, which collectively lead to exceptional mechanical performance, including high strength–ductility synergy, outstanding fracture toughness, and excellent stability over a wide temperature range. As research moves beyond equiatomic systems toward compositionally optimized and application-driven alloys, understanding the link between preparation and processing routes, microstructural evolution, and mechanical behavior has become a central challenge.
This Special Issue focuses on recent advances in the preparation methods and mechanical properties of high-entropy alloys, emphasizing how processing strategies govern phase formation, microstructures, and deformation mechanisms. Contributions addressing casting, thermomechanical processing, powder-based routes, additive manufacturing, and severe plastic deformation are particularly welcome, as are studies exploring strengthening and toughening mechanisms such as solid solution hardening, precipitation, transformation-induced plasticity, and hierarchical microstructure design. Experimental, theoretical, and computational works that establish clear processing–structure–property relationships are encouraged. By bringing together diverse perspectives, this Special Issue aims to provide a comprehensive view of how tailored preparation routes can unlock the full mechanical potential of high-entropy alloys for structural and extreme environment applications.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
