Multi-Functional High Entropy Alloys: From Design to Application

Dear Colleagues,

The emergence of high-entropy alloys (HEAs), defined as multi-principal element alloys, has significantly increased the possibility of discovering new alloys via traditionally uncommon element grouping. Since this design concept of HEAs promises a broad range of compositional flexibility and microstructural complexity, various HEAs exhibiting multi-functional capacities (e.g., superior mechanical properties, corrosion resistance, ballistic resistance, high-strain-rate superplasticity, etc.) have been intensively developed over the past two decades. Moreover, applying novel processes (e.g., hetero-structuring or additive manufacturing) to HEAs let us develop favorable strategies to employ the multi-functionality of the alloys, which greatly promotes the usage of novel alloys in a variety of high-tech industrial applications.

As the scope of the HEA research field mentioned above, the Special Issue on Multi-Functional High-Entropy Alloys: From Design to Application will cover, but will not be limited to, the following topics:

• Alloying/microstructure design;
• Hetero-structuring;
• Additive manufacturing;
• Load-bearing capacity;
• Dynamic behaviors or ballistic performance;
• Superplasticity;
• Corrosion resistance;
• Welding and joining;
• Industrial applications.

It is my pleasure to invite you to submit a manuscript for this Special Issue. We welcome either experimental or theoretical contributions on the above subjects. We hope that the paper published in the Special Issue will advance our understanding of process–structure–property relationships in HEAs for future 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. 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.
