Lightweight Metals: Process, Microstructure, and Properties

Dear Colleagues,

Transportation sector energy consumption is projected to increase year by year. With ever increasing energy consumption depleting energy resources in the world, there is a need to reduce consumption. In addition, nearly one-third of the world’s carbon pollution comes from transportation systems. Therefore, lightweight metals research and development is essential for reducing vehicle/aircraft weight, which can lead to a reduction of fuel consumption, carbon emission, and pollution, and extend their range of travel.

Since the late 1990s, aluminum and magnesium alloys have made their way into mass produced passenger cars. The use of aluminum and titanium alloys in aircrafts also increased. This was the result of newly developed lightweight metal alloys and composites that met mechanical property requirements, as well as advances in processing technologies for lightweight metals. 

This Special Issue on lightweight metals will emphasize the ongoing need for innovation and development of lightweight metal technology. Primarily, it will highlight work addressing the challenges of processing and formability of lightweight metals, while studying the process–microstructure property inter-relationship.  We hope to be able to attract articles covering a broad spectrum of research and technology for lightweight metals based on the following areas: composite lightweight metals, new alloys of lightweight metal development, processing of lightweight metals that covers heat-treatment processing, additive manufacturing processing, and thermomechanical processing.

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-anonymized 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.
