Special Issue Information
Dear Colleagues,
The rapid development of consumer electronics, semiconductors, aerospace, and other fields has increased the demand for ultra-thin and high-performance metal materials. The preparation process of ultra-thin metal materials often needs to undergo super-large plastic deformation, which will have a considerable impact on the microstructure, electrical properties, thermal properties, and mechanical properties of metals. Extra-large plastic deformation promotes a submicron or nanoscale grain size of the metal. Additionally, with cryogenic treatment and other means, some metal grains become extremely nano-sized. The surface energy, grain boundary energy and precipitation behavior of extreme grain refinement combined with ultra-thinning are quite different from those of conventional grain size, resulting in special changes in the corresponding structure and properties. Secondly, in the process of super-large plastic deformation, the plastic deformation mechanism of metal will also appear diversified with a decrease in thickness. In addition, large plastic deformation results in the particularity of the distribution and pattern of the distortion energy of metals, which makes the subsequent texture evolution, precipitation behavior, and recrystallization behavior different from conventional plastic deformation. Large plastic deformation preparation and application of ultrathin metallic materials, including the control of materials in all processing steps, characterization, and, ultimately, performance analysis, are within the scope of this Special Issue. At present, the application scenarios of ultra-thin metal materials are extremely rich and have been widely used in many industries, such as microelectronics, aerospace, new energy, chemical industry, bioengineering, etc.
In this Special Issue, we welcome articles on different types of methods for the preparation, testing and characterization of ultrathin metallic materials and their impact on the final properties.

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 250 words) can be sent to the Editorial Office for assessment.
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.
