Special Issue Information
Dear Colleagues,
Compositionally Complex alloys including high-entropy alloys are a relatively new class of metallic alloys that differ fundamentally from conventional alloys. These alloys exhibit excellent mechanical properties and the phenomena are as yet poorly understood with classical materials knowledge. In conjunction with rapid solidification processes in additive manufacturing, there are opportunities for a wide range of new applications. Therefore, research interest has increased sharply in recent years.
Compositionally Complex alloys consist of multiple elements with similar high atomic fractions and often exhibit single crystalline structures. So far, examples have been reported in which high mechanical strength coupled with high ductility, high strength at elevated temperatures, high wear resistance, or high resistance to corrosion and oxidation have been demonstrated. In conjunction with 3D printing and its high cooling rates, entirely new possibilities arise for complex components that are exposed to extreme conditions, for example, or that can contribute to sustainability and reduced CO2 emissions.
This special issue is intended to reflect the growing interest in these materials in connection with additive manufacturing and offers the opportunity to report on new developments and applications. Basic research-oriented contributions that deepen the understanding of microstructures evolution are considered. Studies describing thermal post-treatments to improve material properties are also encouraged.

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.
