Special Issue Information

Dear Colleagues,

Aerospace materials are a wide family, characterized by their applications under some of the most demanding mechanical, thermal, and thermo-mechanical service conditions. As such, their development has been accompanying technological breakthroughs along the last two centuries, e.g., the development of damage tolerant lightweight alloys contributed to the massification of civil air transport, superalloys are a must in modern jet engines and high temperature alloys are found in all rocket propulsion systems.

Nowadays, current trends in the frame of the so-called “Industry 4.0 revolution”, as well as strict regulations to decrease the ecological footprint of aircrafts, together with new space travel technologies such as reusable entry vehicles are further pushing the development of metal-based aerospace materials and structures and their corresponding manufacturing methods. This Special Issue is devoted to disseminate scientific and technological efforts in this context and it is, therefore, my pleasure to invite you to submit contributions dealing with the processing and behavior under service-relevant conditions of metal-based aerospace materials.

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 papers will be 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 1000 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.

Electromagnetic forming (EMF), a technology with advantages of contact-free force and high energy density, generally aims at forming parts by using a fixed coil and one-time discharge. In this study, multi-stage EMF is introduced to form a panel with stiffened grid ribs. The forming rules of the stiffened panel is revealed via analyzing the distribution and evolution of the simulated stress and strain in the ribs and web, where the grid-rib panels were decomposed as the flat panel and two panels with uni-directional ribs (ribs only in X direction or Y direction). It is shown that the forming depth is mainly attributed to the forces on the web, although electromagnetic force is applied on both the ribs and the web, especially, large force on the ribs. The ribs are subjected to uniaxial stress parallel to their directions, and the web is subjected to plane stress in the deformation region. Furthermore, the change of the uniaxial stress characteristic in the X-direction ribs is influenced by the electromagnetic force, reverse bend and inertial effect. The plastic deformation mainly occurs in the Y-direction ribs of the deformation region under a three-direction strain state. Full article
