Advances in Powder Metallurgy Processes and Materials

Dear Colleagues,

The increasing market share of sintered materials—accompanied by a reduction in the use of traditional manufacturing technologies—represents a clearly observable trend and an important driver for the development of new materials and technologies. Advances in powder metallurgy processes and materials—including control and characterization at all processing stages and analysis of final properties— constitute the main scope of this Special Issue.

From the outset, powder metallurgy methods have been used to manufacture materials for which other shaping technologies cannot be applied. The advantages of these methods quickly attracted new users, expanding their application to a wide range of metals, alloys, and composite structures. The high purity of powders, controlled at production stage, together with the ability to tailor powder size and morphology—which ultimately determine the final properties of products—has made powder metallurgy highly attractive in emerging materials markets. In this context, the sintering process itself remains critically important, as it strongly influences the final microstructure of the material. Staged or simultaneous processes based on controlled force application and temperature fields, as well as additional factors such as the use of electric current, microwave radiation, or laser assistance in advanced processing technologies, enable the production of fully compacted materials without the need for additional post-processing operations.

In this Special Issue, we welcome articles focusing on material preparation methods and their influence on the final performance of products, both at the powder stage and/or during compaction. Of particular interest are fully controllable, fast, and low-cost processes with high implementation potential in advanced powder metallurgy, enabling the production of high-performance materials.

I look forward to receiving your contributions.

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. 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.
