Special Issue Information

Dear Colleagues,

Additive manufacturing (AM) technology is a revolutionary intelligent manufacturing technique that shortens preparation processes, accelerates product iteration cycles, reduces material waste, lowers production costs, and achieves near-net shaping of components with high complexity. Thanks to its unique forming method, which involves rapid cyclic cooling/heating, the resulting alloys usually have heterogeneous structures across scales, contributing to their excellent mechanical properties. However, metal additive manufacturing faces challenges such as thermal cracking tendencies during the solidification process, making it difficult to shape most of the 5500 alloys. Improving AM processes and developing alloys suitable for AM processes is a challenge.

The non-equilibrium solidification process in additive manufacturing introduces new structures, such as abundant dislocations, twinning, and metastable phases, profoundly affecting material deformation mechanisms and ensuring outstanding mechanical properties. Understanding the relationships between process variables, material characteristics, and mechanical performance is crucial for developing high-performance materials. Research in this field explores feasible approaches for shaping advanced new materials through additive manufacturing.

This Special Issue aims to gather original research and high-quality comprehensive reviews in this field, authored by renowned researchers who have made significant contributions to the field of metal additive manufacturing. This focus includes the design of new alloy compositions and widening general knowledge of microstructural evolution and its impact on mechanical properties. Research areas may include (but are not limited to) the following topics:

  • Design of novel alloy compositions for additive manufacturing;
  • Modeling and simulation of additive manufacturing;
  • Design and fabrication of porous metal structures;
  • Gradient heterogeneous materials in additive manufacturing;
  • Microstructural evolution of additive manufacturing materials;
  • Deformation mechanisms and mechanical properties of additively manufactured parts.

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.
