Additive Manufacturing of Metallic Materials: Characterization, Properties, and Modeling

Dear Colleagues,

Additive manufacturing (AM) technologies are positioned to provide a disruptive transformation in how products are designed and manufactured. Metal AM technologies have provided sustainable production routes for metals. There are several advantages related to this technology: design freedom, reduction in raw material consumption, reduced inventory management need, etc. Developing advanced materials with mechanical properties that are superior to existing ones is a constant demand for several challenging applications. Research on this topic aims to explore unique strategies for developing advanced materials via an additive manufacturing route.

However, extending the application of AM to critical components requires a deeper understanding of the correlations between the process variables and the material properties and part geometry. AM is based on adding materials layer-wise and scanning the part geometry using a moving heat source in a prescribed scan pattern. As a result, the cyclic thermal history and cooling rates and, in turn, the microstructural and mechanical properties of AM parts are a function of location and process parameters. Understanding this variation and its correlation to material microstructure, defects, and temperature variations provides a better understanding of the metal AM processes and methods to improve them. The computational modeling of AM processes is one of the approaches taken by researchers in this field to gain an understanding of these correlations. Significant advances in this field have been achieved due to interdisciplinary research in related fields of computational mechanics and numerical methods.

This Special Issue aims to collect the latest developments in the field, written by well-known researchers who have contributed significantly to the field of metal AM.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Innovative AM technologies and process parameter optimization;
• AM process–geometry–property correlations;
• AM process modeling and simulation;
• Design, analysis, and additive manufacturing of porous metallic structures and scaffolds;
• Design and development of TRIP and TWIP alloys, high-entropy alloys, and precipitation-strengthened alloys by additive manufacturing;
• Mechanical and microstructural characterization of AM parts;
• Tensile properties, fatigue, fracture, and failure analysis of AM 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 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.
