Advances in Microstructure and Properties of High Entropy Alloys

Dear Colleagues,

This Special Issue, entitled "Advances in Microstructure and Properties of High Entropy Alloys", provides a focused platform for recent progress in the research and development of High-Entropy Alloys (HEAs)—multi-principal element systems with near-equiatomic compositions. Unlike traditional alloys, HEAs enable novel combinations of strength, thermal stability, corrosion resistance, and wear performance, particularly under extreme conditions.

This Special Issue welcomes studies that investigate the interplay between processing methods—such as casting, mechanical alloying, additive manufacturing, and thermal spraying—and the resulting microstructures, including phase formation, grain refinement, and defect evolution. A key objective is to elucidate how these microstructural features influence mechanical and functional properties. Both experimental and computational works (e.g., DFT, CALPHAD, MD) are encouraged, especially those that advance the understanding of phase stability, deformation mechanisms, and failure behavior. The integration of advanced characterization tools (e.g., in-situ TEM, synchrotron XRD) and machine learning-assisted alloy design is also highly valued. Target application fields include aerospace, energy, defense, and structural materials, with the ultimate goal of guiding the development of next-generation high-performance alloys.

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.
