Design and Performance Evaluation of Additively Manufactured Alloys

Dear Colleagues,

The design and performance evaluation of alloys is an important and rapidly progressing field in modern materials science and engineering, particularly in the context of advanced manufacturing technologies. Additive manufacturing (AM) has revolutionized the production of metal alloys by creating complex geometries that were previously impossible or too costly to produce using traditional methods. Material design is crucial in order to obtain the desired properties from additively manufactured alloys. However, the successful design and printing of functionally graded materials (FGM) and high-entropy alloys remains a challenge for researchers. The microstructure of an alloy—the arrangement of its grains and phases at a microscopic level—profoundly influences its mechanical, thermal, and corrosion properties. By adjusting printing parameters such as the laser power, scanning speed, and cooling rates during the AM process, researchers and engineers can tailor microstructures to enhance the properties of the final product. Meanwhile, simulation and AI-assisted material design are methods with significant applicative potential that should be considered. Moreover, the mechanical, thermal, and corrosion properties of AM alloys are highly correlated with their reliability and safety in real applications. Through testing and analysis, including tensile, fatigue, and impact tests, engineers can understand how the designed microstructure affects the material’s performance and how it can be optimized for the material’s intended use. In brief, mastering the design of additively manufactured alloys and exploring their properties are crucial to producing high-performance customized materials that meet the rigorous demands of modern engineering applications. This Special Issue will summarize recent developments in the design and property evaluation of additively manufactured 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. Crystals 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 2100 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.
