Special Issue Information

Dear Colleagues,

We cordially invite you to publish original scientific articles describing the results of research works or review articles in the Special Issue entitled "Phase and Structure Analysis of Alloys and Metal Matrix Composites—2nd Edition". New metal matrix alloys and composites are materials that can have unique physical, chemical, and mechanical properties. This allows them to be used in numerous and advanced applications. These materials are in the mainstream of global research; therefore, in order to better understand the mechanisms occurring in such materials, and thus model and design them more effectively, it is necessary to fully understand and describe their structure and relate it to the specific properties of these materials.

Therefore, the submitted works may concern both innovative engineering materials, alloys, and composites with modified structures and physico-chemical properties, as well as original technological modifications used in the manufacturing methodology. Papers can also focus on developing new technological solutions and mathematical models to formulate new conclusions.

This Special Issue will provide a detailed review of recent research and developments in the phase and structural analysis of novel alloys and metal matrix composites. We are pleased to invite you to submit your manuscript for this Special Issue. Full articles, announcements, and reviews related to structural characterization are welcome.

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. 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.

Magnesium-based materials are an interesting solution in terms of medical applications. Alloys that are hard to obtain via standard means may be manufactured via mechanical alloying (MA), which allows the production of materials with complex a chemical composition and non-equilibrium structures. This work aimed to investigate materials obtained by the MA process for 5, 8, 13, and 20 h in terms of their phase composition and changes during heating. The results of thermal XRD analysis were in the temperature range between 25 and 360 °C, which revealed MgZn2, PrZn11, Ca2Mg5Zn13, and Ca phases as well as α-Mg and α-Zn solid solution. The structural analysis features the powder morphology of the analyzed samples, showing cold-welding and fracturing processes leading to their homogenization, which is supported by the EDS results. The base Mg-Zn-Ca alloy was modified by different additions, but a thorough analysis of the influence of praseodymium on its thermal properties has not yet been performed. We chose to focus on Pr addition because it belongs to low-toxicity rare earth metals, which is an essential feature of biomaterials. Also, the Ca2Mg5Zn13 phase is not fully known, as there are no crystallographic data (hkl). Therefore, the investigation is important and scientifically justified. Full article
