Special Issue Information
Dear Colleagues,
The mechanical properties of contemporary engineering alloys are reaching their natural limits, despite the fact that the growing human population and transportation networks, energy shortage and ecological problems require even stronger, tougher and lighter alloys, with an extended application temperature range. The mechanical properties originate from the alloy composition and processing history and through the microstructure development. Quite often, a successful processing technology was designed to utilize a particular strengthening mechanism: grain refinement, phase balance, precipitation or solid solution strengthening. This could be determined by particular product requirements, the available equipment, cost, or company tradition. However, new challenges for further property enhancement require a review of the capacity of strengthening mechanisms. Are the precipitates more effective than solute atoms? What is the most reasonable size of grains in a polycrystalline alloy? What state of dislocation structure is required and what criteria define this? How many phases of microstructure do we need? Will the multi-principle element alloys become the future of alloy chemistry? Will the rolling and forging disappear, and will casting, powder pressing and 3D printing dominate in the technology space? Research articles, communications or reviews on these questions are very welcome to this Special Issue, irrespective of alloy composition or processing technology. Feel free to put forward your challenges. Let us discuss the role of strengthening mechanisms in view of their influence on alloy chemistry and technology design.

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.
