Special Issue Information
Dear Collegues,
The atomization of metallic melts is a process that allows the generation of a defined droplet spectrum in the form of a spray. With the knowledge of the processes taking place in the spray, the droplets can be solidified to a metal powder, for example, or large-volume semi-finished products can be spray-formed directly. The atomization conditions and the associated droplet sizes, velocities, trajectories, and concentrations determine the processes taking place in the spray, such as cooling, solidification, and formation of the particle morphology. The history of the droplets determines properties such as their microstructure or flowability, which are important for subsequent processes, such as additive manufacturing or powder metallurgical routes.
The focus of this Special Issue is on the relationship of atomization conditions and resulting material properties. In this context, fundamental investigations on single droplets may be as suitable as investigation on gas atomization processes. Models for the application of detailed findings from single droplets to complex sprays allow the determination of new process windows for atomization.
Contributions should have a focus on the experimental or theoretical analysis of process conditions and their effect on materials properties. Topics may include (but are not limited to):
- Design of atomization processes for metallic melts;
- Experimental process analysis techniques for (local) conditions during melt atomization and in the spray;
- Effect of atomization conditions on resulting powder properties, such as microstructure or powder flowability;
- Spray deposition and spray forming;
- Modeling of atomization processes with metallic melts;
- Fundamental research on single droplet generation, solidification, impact, and deposition;
- Process–structure–property relationships.
It is my pleasure to invite you to submit your manuscript for this Special Issue. Full papers, communications, and reviews are all very welcome.

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.
