Special Issue Information
Dear Colleagues,
Multi-material structures, combining various materials with different functions or properties, are significantly effective for manufacturing high-performance parts and products at low production and operational costs in modern industrial applications. In the automotive industry, for example, multi-material solutions consisting of steel, aluminum, and composites can replace traditional steel structures, resulting in the weight reduction of vehicles and the drastic improvement of fuel efficiency. The multi-material concepts bring many advantages, such as optimizing product design by matching the most-suited material to the required property, and using expensive materials with high-performance only where absolutely necessary, in the other industries.
To build multi-material structures, dissimilar-material welding and joining is required. However, the production of highly reliable multi-material structures is still difficult because many problems arising from metallurgical reactions (the formation of brittle phases), large differences in melting temperature or thermal expansion coefficient between the materials, galvanic corrosion, and so on are inevitable during the dissimilar-material welding and joining. Recently, a large number of academic studies on the welding and joining of several combinations of dissimilar materials using various low-heat-input or solid-state welding and joining processes have been contributing to the development of dissimilar-material welding and joining to create highly reliable multi-material structures, but a vast amount of research and development activities are still needed.
This Special Issue tries to deal with the recent advances in dissimilar-material welding and joining, except for welding and joining of materials with different alloy systems, regarding processing, microstructures, and properties, to develop a deep understanding of the current status and future directions of dissimilar-material welding and joining.

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.
