Special Issue Information
Dear Colleagues,
Dissimilar material structures could realize a combination of dissimilar materials with excellent performance, which improves flexibility in design and production and meets the demand for function and properties in modern engineering structures. These structures have been widely used in many fields due to their higher technological and economic value. Therefore, the reliable joining of dissimilar materials is becoming increasingly important. Nevertheless, the great difference in physical and chemical properties between dissimilar materials poses a huge challenge in achieving reliable joining.
Advances in the joining process of dissimilar materials, including the control and characterization of materials in all process steps and their final performance analysis, are within the scope of this Special Issue. For example, the welding of dissimilar metal materials will inevitably produce a transition layer with a different microstructure and properties from the base metal. Due to the significant differences in element properties, physical properties, chemical properties, and other aspects of dissimilar metals, compared with the welding of the same material, the welding of dissimilar materials is much more complicated than that of the same material in terms of the welding mechanism and operation technology.
In this Special Issue, we welcome articles that focus on dissimilar material joining processes and ways to improve joint performance. The fully controllable, fast, and low-cost process is of particular interest, with a high potential for implementation in the joining of dissimilar materials, which enables the production of high-performance products.

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.
