Special Issue Information
Dear Colleagues,
Tungsten (W) is the metal for extreme environments as it has the highest melting point However, tungsten has two main disadvantages: poor oxidation resistance at temperatures above 600 °C as well as a low room temperature (RT) fracture toughness, KIQ, and a brittle-to-ductile transition (BDT) that occurs at high temperatures. This is why tungsten is currently only used as a functional material and not as a structural material, that is, not for safety relevant, pressurized parts. Consequently, thinking about tungsten as a structural material, the question of how to make tungsten ductile and how to decrease the brittle-to-ductile transition temperature (BDTT) arises.
The purpose of this special issue is thus to compile the current status of work related to the improvement of the properties of tungsten for applications such as fusion, and other extreme environments, e.g. solar thermal power.
Contributions related to the manufacture of new tungsten materials, studies of W-composites, their constituent components as well as modelling and material characterization methods will be accepted.

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.
