Special Issue Information

Dear Colleagues,

The annual world production of aluminum and aluminum alloys has been increasing over the past few decades, reaching a level as high as more than 70 million tons in 2018. The future perspective for this industry is bright, as the applications of Al and its alloys have strongly diversified in the automotive, aerospace, building, and other industries. The main aluminum property is its low density, and more importantly, very high specific properties compared to other metallic and nonmetallic materials. The properties of aluminum alloys can contribute to significant decrease in energy consumption and CO2 emissions, especially in transportation.

The main prerequisite for the future success of aluminum and its alloys is further improvements of existing and the development of novel aluminum alloys. In addition to conventional fabrication methods (casting, forming, powder metallurgy), additive manufacturing technologies enable further tailoring of alloys’ microstructure and obtaining new combination of properties. The properties of aluminum alloys are mainly based on their structure, from the atomic scale to the macrostructure, as seen by the naked eye.

This Special Issue of Metals focuses on relationships between structure and properties of aluminum alloys. The papers presented in this Special Issue give an account of the 2020 scientific and technological state of the art of aluminum alloys (see the Keywords/Topics below). Your contribution to this 2020 account is highly valuable and appreciated. We invite you to contribute research work that studies the effect of manufacturing on structure of aluminum alloys and that relates the structure with different properties.

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 1600 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.

Research on Laser-TIG Hybrid Welding of 6061-T6 Aluminum Alloys Joint and Post Heat Treatment
Metals 2020, 10(1), 130; https://doi.org/10.3390/met10010130 - 15 Jan 2020
Abstract
The 6061-T6 aluminum (Al) alloys was joined by the laser induced tungsten inert gas (TIG) hybrid welding technique. It mainly studied the influences of welding parameters, solution, and aging (STA) treatment on the microstructure and tensile properties of Al alloy hybrid welding joints. [...] Read more.
The 6061-T6 aluminum (Al) alloys was joined by the laser induced tungsten inert gas (TIG) hybrid welding technique. It mainly studied the influences of welding parameters, solution, and aging (STA) treatment on the microstructure and tensile properties of Al alloy hybrid welding joints. Microstructures of the joints were also analyzed by optical microscopy and transmission electron microscopy. Results showed that the laser induced arc hybrid welding source changed the microstructure of the fusion zone and heat effect zone. STA treatment effectively improved the mechanical properties of the softening area in the hybrid welding joint, whose values of the tensile strength and elongation were on average 286 MPa and 20.5%. The distribution of the reinforcement phases and dislocations distributed were more uniform, which improved the property of STA treated joint. Full article
