Special Issue Information

Dear Colleagues,

In the past 20 years, magnesium alloys and composites have gained superior prominence in weight-critical applications in the aerospace, automotive, and transportation sectors. In recent times, magnesium’s ability to degrade in the human body has made it a potential material for orthopedic implants. In research, several different approaches have been used to improve the properties of magnesium-based materials by means of alloying, composite technology, heat treatment, and coatings, among others. Using microstructural control, the overall properties of magnesium and its alloys have been improved by researchers around the world. Furthermore, the use of unique processing technologies such as additive manufacturing, microwave sintering, extrusion, etc., have been able to deliver high-performance, lightweight magnesium-based materials. The combined effect of processing technology and novel alloying elements or reinforcements can be vital in achieving greater acceptance of magnesium-based materials in industry.

Accordingly, this Special Issue aims to explore research articles focused on the use of novel processing technologies and their effect on the properties of the developed magnesium-based materials. Review articles are also welcome.

Topics falling under the scope of the issue, among others, are:

  • Novel processing of magnesium-based materials;
  • Structure–property relationship in magnesium-based materials;
  • Additive manufacturing of magnesium-based materials;
  • Magnesium processing through recycling;
  • Surface property characterization (corrosion, tribology, etc.) of magnesium-based materials.

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.

In this study, a Mg3Zn alloy and a Mg3Zn1HA nanocomposite were fabricated through disintegrated melt deposition, followed by the hot extrusion process. The specimens were subjected to fiber laser surface modification in air and demineralized water (DM) medium to determine the influence of the laser treatment medium on the microstructure, microhardness, grain size, and surface topography. During the laser treatment, the samples under the water medium produced a lower surface roughness when compared with the air medium. The atomic force microscope (AFM) surface topography scan showed the presence of surface modifications caused by the presence of nanohydroxyapatite (nHA) in the matrix, resulting in a 367.4% and 632.4% increase in the surface roughness (Ra) in the Mg3Zn1HA nanocomposite when compared with the Mg3Zn alloy in water and air media, respectively.
