Special Issue Information

Dear Colleagues,

Spark Plasma Sintering (SPS) and field-assisted consolidation technologies are representing a great opportunity for the production of new materials. Nevertheless, the challenge to achieve properties that cannot be obtained by other conventional methods is strictly related to know-how of this fast sintering process, which permits the production of near full dense materials, using lower temperatures and shorter time. The combination of SPS with severe plastic deformation processes like mechanical milling has been proved to be a suitable route for the development of nano- and ultrafine grained materials. Mechanical alloying with ceramic reinforcement has extended the benefits of SPS to the fabrication of composite materials. Moreover, SPS has also been successfully used for the development of functionally graded materials (FGM) and materials for many other applications.

Aim of this Special Issue is to collect full papers, communications, and reviews reporting original and novel results about SPS and field-assisted consolidation technologies of metals, alloys, and composite materials.

I cordially invite you to send 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 papers will be 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 1000 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.

Mg matrix in situ composites were fabricated from Mg and ZnO powder by a spark plasma sintering method. The composition and microstructure of the sintered samples were characterized. Corrosion properties of fabricated composites were evaluated by immersion and by electrochemical tests using Hanks’ solution. The results showed that the formation of in situ products improved significantly the corrosion resistance of the fabricated composites compared with pure Mg; Mg-10 wt % ZnO composites especially exhibited the lowest corrosion rate. In addition, an energy-dispersive X-ray (EDX) analysis showed that calcium phosphate formed as a corrosion product on the surface of Mg-10 wt % ZnO composites, while Mg(OH)2 appeared as a corrosion product on the surface of Mg-20 wt % ZnO composite. The findings suggested Mg-10 wt % ZnO composite as a potential candidate for temporary implant application. Full article
