Dear Colleagues,
For modern-day industrial applications, metals and alloys should have mechanical properties such as high strength, high ductility, high fracture toughness, and high stiffness, preferably together with high temperature capability, high corrosion resistance, as well as low weight and low cost. Since such a metal currently does not exist, C. Suryanarayana called this metal utopium in his article “Mechanical Alloying: A Novel Technique to Synthesize Advanced Materials” in AAAS Research, Vol. 2019, Art. 4219812. One promising pathway towards developing materials with property combinations closer to utopium is mechanical/mechanochemical synthesis of alloys.
Mechanical/mechanochemical synthesis consists of non-equilibrium processing routes involving severe plastic deformation (SPD) that often leads to unexpected alloy properties, frequently nearer to utopium than the base metals. There has been a remarkable evolution of these methods since they were developed in the 1960s; however, it should be mentioned that mechanochemical methods have already been used as early as 300 BC. Mechanical alloying is one of these routes, high-pressure torsion, cold wire drawing, and accumulative roll bonding are three others. When applied to alloys, SPD often leads to mechanically driven phase transformations like forced mixing in immiscible alloy systems, decomposition of supersaturated solid solutions, dissolution of second phase particles, or even amorphization. These reactions justify the expression “mechanochemistry”.
This Special Issue will present the latest developments and findings in the area of mechanical and mechanochemical synthesis of alloys. The scope includes (but is not limited to) new alloys processed by these methods, their microstructural evolution, mechanical properties, failure/degradation analysis, fracture, fatigue, wear, and corrosion characteristics, in brief, the approach of these alloys to utopium. Theoretical and/or computational treatment of these phenomena, as well as application-related aspects, are also 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. 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.
