Special Issue Information
Dear Colleagues,
Friction stir welding is a relatively novel solid-state joining technology. Due to the solid-state nature of welding process, FSW avoids undesirable solidification phenomena and thus routinely produces sound welds with excellent mechanical properties even in aluminum alloys which are conventionally considered to be “unweldable”. The numerous advantages of this technique include low energy consumption, high productivity, and flexibility. It is also important to emphasize that FSW is a “green” technology, which requires no shielding gases and filler materials. As a result, FSW is widely used in industry, often being considered one of the most significant recent achievements in material joining. Moreover, as the welded material normally undergoes very large strain at high temperatures, FSW typically results in the formation of fine-grained microstructures. The fine-grained characteristics of this process have enabled its application in material processing. This derivation of FSW technology is known to as friction stir processing (FSP).
Though the fundamental concept of FSW/P is remarkably simple, the welding process involves very complex metallurgical phenomena, and despite an impressive recent progress in their investigation, many important aspects are still unclear. Hence, the aim of this Special Issue is to present new achievements in the friction stir welding/processing of aluminum alloys, new tendencies in technique developments, theoretical and experimental studies of FSW/FSP, microstructure evolution and influence on mechanical properties, and processes of recrystallization and precipitation.

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.
