Additive Manufacturing of Special Alloys

Dear Colleagues,

This Special Issue explores the latest advancements, challenges, and applications of additive manufacturing (AM) techniques for producing high-performance special alloys, including nickel-based superalloys, titanium alloys, high-entropy alloys, and other advanced metallic materials. This Special Issue highlights innovative research on process optimization, microstructure control, and mechanical property enhancement to meet the demanding requirements of the aerospace, biomedical, energy, and defense industries. Contributions cover a wide range of topics, such as powder feedstock development, laser/electron beam melting, directed energy deposition, post-processing strategies, and computational modeling of AM processes. Particular emphasis is placed on overcoming defects including porosity, residual stresses, and anisotropic behavior, as well as tailoring alloy compositions for superior performance. By integrating experimental and theoretical approaches, this Special Issue provides valuable insights into the scalability, sustainability, and industrial adoption of AM for special alloys. Researchers, engineers, and industry professionals will find this Special Issue to be a comprehensive resource for understanding the state of the art in metal AM and its future directions.

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. Applied Sciences 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 2400 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.
