Special Issue Information

Dear Colleagues,

The global aluminum market was valued at USD 229.85 billion in 2023 and is projected to grow from USD 243.89 billion in 2024 to USD 393.70 billion by 2032. Aluminum and its alloys are silvery-white, non-magnetic, and ductile metals that play a critical role in the automotive, aerospace, building, and other industries. Moreover, the manufacturing process significantly influences the microstructures and properties of aluminum alloys. Therefore, the development of new aerospace aluminum alloys and automotive lightweighting is crucial.

With the increasingly serious environmental and energy crisis, some aluminum alloys that have undergone special and short processes have been gradually employed to product manufacturing in recent decades. This has occurred due to their characteristic benefits, including low investment costs, low energy consumption, and high efficiency. However, until now, not many research studies have been published on the special and short processes of aluminum alloys compared to traditional processing routes.

This Special Issue of Metals focuses on the short and special processes of aluminum alloys. The papers presented in this Special Issue provide an account of 2024’s scientific and technological state of the art special and short processes of aluminum alloys (see the Keywords/Topics section below). Your contributions to this compilation will be highly valuable and appreciated. We invite you to contribute research studies on the effects of short and special processes in relation to the microstructures and various properties of aluminum alloys.

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.

Abstract
Standard AA5083 (ZSE000), AA5083 modified with 0.3 wt.% Zr and 0.3wt.% Sc (ZSE330) and AA5083 modified with 0.3 wt.% Zr, 0.2wt.% Sc and 0.1wt.%Er(ZSE321) sheets were fabricated through a short process (including a simulated twin-belt continuous casting, subsequent direct rolling, intermediate annealing, cold [...] Read more.
Standard AA5083 (ZSE000), AA5083 modified with 0.3 wt.% Zr and 0.3wt.% Sc (ZSE330) and AA5083 modified with 0.3 wt.% Zr, 0.2wt.% Sc and 0.1wt.%Er(ZSE321) sheets were fabricated through a short process (including a simulated twin-belt continuous casting, subsequent direct rolling, intermediate annealing, cold rolling and stress-relief annealing) to systematically investigate the influence of partially substituting Er for Sc on the microstructure, mechanical properties and corrosion resistance of short-processed Al-4.7Mg-0.6Mn-0.3Zr-0.3Sc sheets. The results show that ZSE321 presents the optimal tensile properties (UTS: 541 MPa; 0.2%PS: 469 MPa and EF:7.7%) among the three experimental sheets. This is attributed to significant grain refinement, the inhibition of the recrystallization and promotion on the precipitation of Al3(Sc, Zr, Er) nanoparticles. Furthermore, the corrosion properties of the experimental sheets were also explored in this study, and the short-processed ZSE321 sheet presents the optimum corrosion resistance. Full article
