Special Issue Information
Dear Colleagues,
Powder metallurgy and additive manufacturing technologies offer numerous advantages in the field of metal materials. These include the ability to fabricate complex shapes, efficient material utilization; preparation of specialized performance materials; and their high forming rates, rapid manufacturing, and customization and multi-material and composite material production, as well as their quick iteration and design optimization. With continuous improvements in raw material preparation techniques and process equipment, the application areas of powder metallurgy and additive manufacturing in metal materials are expanding. In particular, these technologies demonstrate significant advantages in areas such as special compositions and performances, efficient manufacturing of complex structures, etc. Examples include large-sized titanium alloy structures for aerospace applications, nickel-based high-temperature alloys for aerospace engines, high-strength steels, corrosion-resistant medical devices, aluminum alloys, copper alloys, and other metal and alloy materials.
Powder metallurgy and additive manufacturing technologies in material preparation are influenced by factors such as powder selection and availability (particle size, loose packing density, and flowability), process parameters and optimization (powder blending, forming method, sintering temperature and time, sintering atmosphere, heat treatment, laser power, scanning speed, and support structure), equipment and technology maturity, cost and economy, quality control and performance verification, and standards and specifications. Therefore, this Special Issue welcomes research articles and reviews on the powder metallurgy technology and additive manufacturing technology of metal and alloy materials in material selection and optimization, process parameter optimization, microstructure and performance research, high-entropy alloy and composite materials, etc.

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. Metals 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 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.
