Special Issue Information
Dear Colleagues,
The high melting temperature, high strength at elevated temperatures, low thermal expansion, and high heat conduction of refractory metal alloys make them a favored candidate material for terrestrial energy production
facilities. Niobium, molybdenum, tantalum, tungsten, and their alloys are fabricated as powders through the reduction of their oxides, consolidation by sintering, activated sintering, or liquid phase sintering. Heavy tungsten alloys bound by nickel, iron, or copper are used as radiation shields, balancing weights, and penetrators. At higher temperatures, refractory alloys are used for tools and molds for metal and glass forming and in load-bearing parts of jet engines. At higher temperatures under a protective atmosphere, tungsten is used for heating filaments and elements, and electrodes are used for welding. The strong chemical bonds of refractory metals make their microstructure stable and generate potential for developing high-strength alloys for elevated temperature service. However, applications are limited by the brittle–ductile transition at relatively high temperatures and their high reactivity with oxygen, as well as the volatility of their oxides. These limitations are encountered by alloying with other refractory metals. The high bond strength and high atomic mass make them stable against radiation damage, and therefore leading candidates for the first wall material in fusion reactors.
A Special Issue of Metals will be devoted to the physical metallurgy of
refractory alloys. It intends to give an account of the scientific and technological state of the art of recent and potential developments of refractory alloys and environmental protection (see the Keywords/Topics below). Your contribution to this work will be highly valued and appreciated

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.
