Special Issue Information
Dear Colleagues,
Due to the pressing demands for weight reduction and energy efficiency in both land and air transportation, the usage of lightweight materials has been increasing rapidly in recent years. As one of the lightweighting structures, tailor welded blanks (TWBs) are single-piece semi-finished parts produced by joining sheets of the same or different gauges or sheets of different alloys using a variety of welding methods. Typical joining technologies involve arc welding, tungsten inert gas welding (TIG), laser beam welding (LBW), friction stir welding (FSW), etc.
This Special Issue focuses on the Properties of Welded Metallic Materials. As such, the scope is somewhat broad and includes properties related to all techniques mentioned above. For example, laser welding has been attractive for industrial applications due to its high productivity, flexibility, reliability and precision. However, aluminum alloys are some of the most challenging metals to weld by laser. Friction stir welding is a solid-state welding technique developed to join parts comprising either the same or different materials. Researchers have found that the properties of welded materials are significantly affected by welding parameters (power source, welding speed, etc.), especially for heat-treatable alloys. This is because different welding parameters result in different weld shapes, microstructures, phase distributions, or temper conditions, leading to significant variations in the post-welding properties.
For this Special Issue, we look forward to articles investigating the underlying mechanisms between welding processes and microstructure, which eventually determine the post-welding properties. We also welcome the submission of papers reporting on the development of numerical models for welded materials which can simulate deformation behavior or predict mechanical properties under complex loading conditions.

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.
