Dear Colleagues,
Over the past decade, a radically new alloying strategy has emerged with the enormous potential to make a great impact on the way materials are developed today. Traditionally, metallurgists have added small amounts of certain elements to tailor the properties of an alloy with one principal element. Even though properties can effectively be modified this way, the approach in itself is very limiting. The new alloying strategy involves the combination of multiple principal components in relatively high concentrations, which gives rise to the so-called high-entropy alloys. Because, in recent years, the progress with traditional materials has slowed down, researchers are now looking for alternative solutions. High-entropy alloys can potentially provide unique tailored solutions due to the large number of possible combinations of elements to create new materials with improved properties. Particularly, the possibility of overcoming dilemmas and barriers associated with traditional alloys, such as strength ductility trade-offs, makes high-entropy alloys a very exciting type of materials. The challenges to overcome come from the great number of possible element combinations to form high-entropy alloys. Hence, the combined efforts of experimental work and computational modeling is needed for these materials to reach their full potential. The growing relevance of these materials has been broadly recognized, and recently, they have been identified as the number one topic of the upcoming decades. This Special Issue reviews the latest technological applications and advances of high-entropy 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 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.
