Special Issue Information
Dear Colleagues,
Manganese steels have been continuously studied since the publication of an article entitled, “Hadfield’s Patent Manganese Steel” in the 8 February 1884 edition of “The Engineer”. Incredibly, 136 years on, few areas of physical metallurgy still generate as much excitement and activity as the study of medium and high manganese steels. The current wave of interest began in the mid-1990s/early 2000s, triggered by the development of cold-rolled 2G and later 3G sheets to meet more stringent automotive weight reduction and crash resistance requirements. Some of the new alloys have already found their way into the automotive marketplace; many others are close to commercial production. A multitude of other, non-automotive, applications is also being enthusiastically pursued. These include shape memory alloys, steels for ballistic protection, cryogenic containers, medical stents, tank cars, slurry pipes, alloys for additive manufacturing, etc.
This Special Issue is intended to provide a broad forum for the latest results in the physical metallurgy of these fascinating steels. This includes fundamental questions regarding phase transformations and strain hardening mechanisms such as the relative importance of mechanical twinning and DSA in TWIP steels, and the factors governing the nucleation, growth and stability of austenite islands in TRIP alloys. Strain partitioning, size effects, extended Lüders plateaus and the origin of negative strain rate sensitivities are all crucial aspects that require much better understanding. Fracture properties and especially the sensitivity to hydrogen embrittlement are equally important subjects for research. Contributions on these and other topics related to the processing, testing, characterization and applications of modern manganese steels are invited.

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.
