Special Issue Information
Dear Colleagues,
High-entropy alloys have been proposed for nearly 20 years. This kind of alloy has multiple principle elements, subverting the traditional thinking of alloy design, and offers a very large compositional region with almost unlimited possibilities. During the last 20 years, the understanding of high-entropy alloys has continuously changed and progressed. At first, high-entropy alloys were strictly defined as those comprising five or more elements with exactly the same composition ratio. Later, it was found that this definition limited the development of high-entropy alloys, and only then did non-equiatomic high-entropy alloys and medium-entropy alloys come into being. Another example is that the initial research on high-entropy alloys was only in several solid-solution-state structures like FCC or BCC, and later it was found that non-solid-solution-state high-entropy alloys also show excellent properties. Another transformation is that the research on high-entropy alloys has expanded its focus from the main mechanical properties to include the study of various properties, such as magnetic properties, corrosion properties, and radiation resistance. We are still in the early stages of high-entropy alloys research, and we look forward to the greater potential of these alloys in the decades to come.
This Special Issue of Metals focuses on works related to high-entropy alloys towards industrial application. We hope that this Special Issue will include articles reporting research on high-entropy alloys giving impetus to their industrial application. Any research on the properties and structures of these alloys is more than welcome.

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.
