Special Issue Information
High-entropy alloys (HEAs), also known as multiprincipal element alloys (MPEAs) or complex concentrated alloys (CCAs), are a new class of materials developed based on “chemical disorder”, which breaks the limitations of only one or two principal elements in traditional materials. HEAs are expected to act as competitive candidates of structural materials in industrial, aerospace, and biomedical applications. To promote their wide engineering applications, it is desirable to improve the strength of the alloys while retaining a good ductility. To date, as a structural material with excellent performance, HEAs have not been applied in large-scale industrialization yet. The main reasons are as follows: (i) Most HEAs find it difficult to balance plasticity and strength. For example, face-centered cubic (FCC) HEAs have good elongation but low strength, while body-centered cubic (BCC) HEAs show high strength but poor ductility; although hexagonal close-packed (HCP) HEAs can be used as magnetic functional alloys, the research on mechanical properties of the HCP-structured HEAs is still in its infancy. (ii) Moreover, the poor fluidity, castability, and composition segregation of HEAs are also important factors affecting technical applications. (iii) The costs of raw materials, preparation, and recovery of HEAs are normally expensive compared with those of Al alloys, Ti alloys, steels, and other traditional alloys. Therefore, HEAs must overcome the abovementioned drawbacks and achieve an optimal combination of high strength and good plasticity.
This Special Issue will cover new findings in the field of the strengthening and toughening of HEAs, including FCC HEAs, BCC HEAs, dual-phase HEAs and refractory HEAs. Manuscripts describing new experimental and theoretical studies on these fields are highly welcome in this issue.

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. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
