Advances in Microstructure Evolution and Mechanical Properties of Additively Manufactured Metals and Alloys

Dear Colleagues,

Additive Manufacturing (AM) has fundamentally transformed the landscape of Metallurgical and Materials Engineering, enabling the production of complex geometries that were previously impossible to fabricate. However, the unique thermal histories inherent to processes such as Laser Powder Bed Fusion and Laser Directed Energy Deposition—characterized by rapid solidification rates and cyclic reheating—induce distinct microstructural features that differ significantly from their wrought or cast counterparts. The reliability of AM components in safety-critical applications, particularly within the aerospace and energy sectors, depends entirely on our ability to predict and control these features.

This Special Issue seeks to advance the fundamental understanding of the material–process–performance relationship. We invite submissions that investigate the link between AM processing parameters and Microstructural Evolution, focusing on how non-equilibrium phases, grain morphology, and texture influence final mechanical behavior.

We are particularly interested in research pushing the boundaries of material capability, including the fabrication of High-Entropy Alloys and Refractory and High Temperature Alloys. As these advanced materials offer superior resistance to extreme environments, understanding their microstructural response to the AM thermal cycle is critical for their adoption.

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.
