Special Issue Information
Dear Colleagues,
The mechanical and physical properties of hexagonal metals began being studied later than those of cubic metals. This was due to the fact that the most used metals and alloys in the industry were iron, steel, or aluminum and aluminum alloys. In the last few decades, various industrial branches have expressed an increasing interest in hexagonal metals and alloys (mainly Mg, Ti, and Zr alloys): The 3C industry, transportation industry, nuclear devices, and industrial production of metallic parts for biomedical applications. On the other hand, hexagonal crystals exhibit a lower symmetry compared to cubic crystals. This has a consequence in the anisotropy of the mechanical and physical properties. The anisotropy of hexagonal metals and alloys depends on the axes’ ratio c/a. In the first group, where c/a > 1.63 (the ideal ratio for close packing), the basal planes (0001) are the close packed planes (Zn, Cd, Mg), whereas in the case when c/a < 1.63 (Zr, Ti, Be), the close packed planes are prismatic ones . Deformation mechanisms, texture formation, and other physical properties are different for both groups of hexagonal metals.
Deep knowledge of the mechanical behavior and physical properties of these materials may facilitate the search for materials with predetermined characteristics. The purpose of the papers submitted to this Special Issue is to extend our current knowledge of the mechanical and physical properties of metallic hexagonal single crystals and polycrystals. Your contributions are 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. Crystals 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.
