Lightweight Alloys for Aerospace Applications

Dear Colleagues,

The strong competition in the industrial aerospace sector pushes towards the production of aircrafts with reduced operating costs through an extended service life, better fuel efficiency, and increased payload and flight range. In this perspective, there is an increasing demand of new materials and/or materials with improved characteristics to reduce the weight of mechanical components and structures; thus, lightweight alloys and their composites play a key role.

Light metal alloys are largely used in the structural parts of aircrafts and cold sections of engines (fan, compressor, and casing). In recent years, breakthrough advancements have been made for improving the mechanical performances and corrosion resistance of aluminum, magnesium, and titanium alloys by means of composition tailoring, grain refinement, precipitation of second phases, and control of microstructural features on a nanoscale.

Moreover, the sustainable technological development has become a dominant paradigm today and imposes an optimized use of resources, a lower energetic impact of industrial processes, and new tasks for materials and products.

New results are continuously published in the scientific literature. The Special Issue aims to collect both review and research papers from academic and industrial investigators focused on recent advancements in lightweight alloys, novel processes, and testing methods for aerospace applications. We hope this could be a way to stimulate fruitful networking on an international scale and cooperation among authors and readers operating in this research area.

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.
