Recent Application of Powder Metallurgy Materials

Dear Colleagues,

The earliest large-scale industrial application of powder metallurgy (P/M) involved the production of tungsten filaments for light bulbs in the beginning of the 20th century. Since then, P/M technology has been increasingly used to manufacture a wide variety of structural parts, tools and specialty materials. Powder metallurgy has also become the method of choice for creating composites. It enables the production of materials that cannot otherwise be obtained, such as some electrical contacts (W-Cu, W-Ag, Cr-Cu and Cu-C), cemented carbides (WC-Co and WC-TiC-Co), self-lubricant bearings, filters and flame arrestors, metal matrix friction materials, magnets, etc. More recent developments in P/M processing techniques such as warm compaction, hot isostatic pressing, powder injection molding and additive manufacturing, to name a few, provide an opportunity to fabricate high-density materials and complex-shaped parts that are difficult to form or machine by conventional methods. Therefore, this Special Issue is addressed to all P/M specialists, from both industry and academia, who are willing to share knowledge about new sintered materials, their areas of application and the latest innovations in P/M processing techniques.

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.
