Advances in Physical Metallurgy of Additively Manufactured Alloys

Dear Colleagues,

The Special Issue titled "Advances in Physical Metallurgy of Additively Manufactured Alloys" explores the intricate landscape of additive manufacturing (AM) applied to metallic materials. We seek submissions that delve into the microstructure–property–processing relationship in metals and alloys manufactured through various AM technologies, encompassing various materials from nickel and titanium alloys to steel and high-entropy alloys. Powder bed fusion, direct metal deposition, and cold spray additive manufacturing are among the targeted technologies. Contributions examining microstructural characterisation after various post-treatments are encouraged. This interdisciplinary endeavour aims to bridge the gap between traditional physical metallurgy and the unique challenges posed by AM by addressing barriers like material selection, consistency, repeatability, accuracy, and post-processing requirements in AM. These are pivotal for the widespread adoption of AM. Therefore, we encourage submissions that drive the progress of technical innovation, process optimisation, and material development.

By fostering collaboration and disseminating cutting-edge research, this Special Issue aims to accelerate the development of AM-manufactured alloys for various industries, including aerospace, automotive, maritime, and biomedical. Full papers, short communications, case studies, and reviews advancing our understanding and application of physical metallurgy in additive manufacturing are welcomed.

I look forward to receiving your contributions.

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. Materials is an international peer-reviewed open access semimonthly 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.
