Deformation Behavior of High-Entropy Materials

Dear Colleagues,

In the early 21st century, a novel alloying strategy was introduced to create new materials called high-entropy alloys (HEAs), which involves the combination of multiple principal elements in relatively high concentrations. Interestingly, many HEAs have been reported to form simple (e.g., body-centered cubic (bcc), face-centered cubic (fcc), and hexagonal close-packed (hcp)) yet chemically disordered solid-solution phases. In addition, these alloys display a variety of technologically appealing and tunable properties, such as outstanding mechanical properties, encouraging fatigue resistance, and superconductivity. Recently, the concept of HEAs has been extended to other types of materials, e.g., ceramics, composites, and amorphous. The term HEMs, i.e., high-entropy materials, is named to cover all of the related materials that are based on the multi-principal-element concept.

Nowadays, HEMs are becoming the main subject matters of non-equilibrium materials and are expected to lead to breakthrough advances and superior performance in a wide array of applications. Although their promise is great, exploring the enormous number of HEM compositions, as well as their structure–property relations, is currently one of the biggest challenges. This Special Issue aims to address the up-to-date theoretical and experimental research on HEMs. Specific topics of interest include but are not limited to: (i) computational and experimental design of HEMs; (ii) phase transformation mechanisms in HEMs; (iii) mechanical properties of HEMs at cryogenic and elevated temperatures; (iv) transformation induced plasticity (TRIP) and/or twinning induced plasticity (TWIP) effects in HEMs, and their influence on mechanical properties. Submissions of reviews and research articles are all welcome.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.
