Dear Colleagues,

The upcoming Special Issue will focus on the " Recent Developments in Powder Metallurgy". The boundaries of Powder Metallurgy have now been extended to cover the processing, microstructure, properties, and applications of consolidated powders of difficult-to-process materials. Examples include titanium, its alloys, and titanium matrix compounds. Components having intricate shapes and possessing superior physical and mechanical properties are, nowadays, produced for aerospace, medical, and marine applications, although further research is being carried out in order to refine the processes and optimize the process parameters.

Among the processes that are gaining wide-spread industrial applications are Electron Beam and Laser Beam Additive Manufacturing (EBAM and LBAM), particularly when consolidating powders such as Ti-6Al and Ti-Al-4V. Both processes are, in fact, descendants of rapid prototyping, and enable manufacturing full dense components additively, layer-by-layer directly from a CAD file.

Another innovative process is Metal Injection Molding (MIM), which is mainly used for stainless steel, low-alloy nickel steels, magnetic alloys, tungsten, and high performance alloys, such as Inconel 718 and 625, Hastelloy, and superalloys.

There is also an emerging interest in producing components combining both wrought and PM parts, which posses superior vibration damping and sound deadening properties. These two dissimilar parts are combined through appropriate welding, brazing, or diffusion processes.

Equally important, newly developed materials and innovative processing of conventional materials enabled the achievement of superior properties that were not attainable before. Super austerities stainless steel, nitrogen solid-solution strengthening of PM titanium, and Ti Ni shape-memory alloys with added TiO2, are some examples.

Papers on the refinement of EBAM, LBAM, MIM, and the joining of wrought and porous metals, through experimentation and analysis or mathematical modeling are of particular interest and are invited for inclusion in this Special Issue on the "Recent Developments in Powder Metallurgy. Current Review articles of those processes in the industry are also welcomed.

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.
