Special Issue Information
Dear Colleagues,
The emergence of multiprincipal element alloys (MPEAs), known as high-entropy alloys (HEAs) and medium-entropy alloys (MEAs), has significantly increased the possibility of discovering new alloys via traditionally uncommon element grouping. Since this design concept of MPEAs is promising a broad range of compositional flexibility, various MPEAs exhibiting multifunctional performances have been developed over the past two decades. Moreover, beyond the advantages of compositional complexity of this type of alloys, most material scientists have attempted to finetune the microstructure to overcome the limitation of the property window of MPEAs via grain refinement, precipitation hardening, or heterostructuring.
Based on the compositional flexibility of MPEAs, controllable microstructural factors are diverse, and these microstructural factors complicatedly affect the properties of MPEAs. In order to develop a novel strategy for effectively tailoring the multifunctional performance of metallic materials, a comprehensive understanding of the relationship between microstructure and properties is needed. As per the scope of research field mentioned above, the Special Issue on “Multifunctional High-Entropy Alloys: Relationship between Microstructure and Property” will cover but will not be limited to the following topics of MPEAs:
- Alloying/microstructure design;
- Heterostructuring;
- Additive manufacturing;
- Heterogeneous microstructure;
- Load-bearing capacity;
- Functional properties;
- Structure–property linkage.
It is my pleasure to invite you to submit a manuscript for this Special Issue. We welcome either experimental or theoretical contributions to the above subjects. We hope that the papers published in the Special Issue will advance our understanding of microstructure–property relationships in MPEAs for developing multifunctional metallic materials.

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. Materials is an international peer-reviewed open access semimonthly 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.
