Special Issue Information
Dear Colleagues,
The goal of this Special Issue is to review various applications and technologies of research on nanostructured metallic materials, which have been rapidly diversifying in recent years. The first nanostructured metallic materials (NMMs) were developed in the early 1990s as structural materials with unique mechanical and physical properties, including abundant high-angle grain boundaries. In addition to the improvement of mechanical properties, the scope of research was gradually expanded as NMMs exhibited excellent functional properties in various applications, such as soft magnetic materials and highly active catalysts. In general, NMMs include various types of defects such as grain boundaries, stacking faults, twin boundaries, and nanovoids. Additionally, they exhibit lower activation energy and thus have a high potential to expand into various application fields utilizing the reaction of metal atoms on the surface.
Recently, the introduction of the nanostructure in advanced engineering alloys is spreading, in the form of new deformation mechanisms being developed or novel concepts such as damage tolerance and self-healing being proposed. In addition, new processes for manufacturing nanoparticles, nanofoams, and nanocomposites have been actively developed. Due to their large surface area, these novel NMMs exhibit high activity as various functional materials, such as electrodes for water splitting and dye degradation, exhibit new phase transformation behavior by affecting phase stability, and improve toughness by inhibiting crack propagation. Furthermore, nanostructure design is emerging as a major concern in additive manufacturing and combinatorial deposition. As it has been studied in such a variety of application fields, it is necessary to organize and understand the correlation between interdisciplinary studies. In this Special Issue, we hope to review the current status of nanostructure design and understand the challenging fundamental issues common to various metallic materials applications.

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.
