Special Issue Information
Dear Colleagues
Aluminum and magnesium alloys (lighweight alloys) play a crucial role in the development of engineering materials due to their ability to improve mechanical performance through different routes, such as alloying elements, variations in processing routes, and heat treatments. Furthermore, their ability to form composites using various reinforcing materials of different natures (such as oxides, carbides, nitrides, or carbon nanotubes) increases their range of applications. These composites can be strengthened by decomposing a super-saturated solid solution (forming a precipitate dispersion) or introducing insoluble phases into the metallic matrix. Dispersion-strengthened materials belong to the composite material group; their structure is formed by a polycrystalline matrix into which dispersed particles are incorporated (mainly oxides, carbides, and nitrides). The dispersoid strengthening effect is based on the obstruction of dislocation movement, dislocation density increase, and grain refining. The strengthening effect of the dispersoids depends on their type, size, morphology, volume fraction, and distribution. Their resistance against dissolution and coalescence is also key (particularly at high temperatures). The exciting field of lightweight metal matrix composite materials is still waiting to be fully explored by material scientists. Thus, this Special Issue will strengthen the current understanding, design, synthesis, and development of these materials, to provide a platform for combining high-quality research and innovative ideas and to bridge the gap between fundamental research and technological applications.

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.
