Special Issue Information

Dear Colleagues,

As demonstrated more than a decade ago, ferrite-austenite and martensite-austenite steel microstructures can provide enhanced strength-ductility combinations, improved with the increasing austenite fraction. In addition to the amount of austenite, its stability under deformation is of high importance concerning the transformation-induced plasticity and possible twinning-induced plasticity effects and thereby high ductility.

Fully austenitic TWIP-steels have outstanding properties in terms of strength and ductility combination, but there is a serious problem in terms of mass production of these steel: the high costs not only of the raw materials, but also of the production process. Further, certain embrittlement phenomena have limited their application. For these reasons, the Mn content in the steel needs to be reduced to an industrially appropriate level.

Indeed, medium-Mn steels containing 3%–11% Mn have reached much attention lately. Excellent properties of medium-Mn steels were invented and reported already in the early 1970s, but the interest has recently exploded with respect, particularly, to automotive applications. As such, a material, medium-Mn high-strength and ultra-high strength steels was developed in order to enable lightweight car body design and improved passenger safety features. However, the optimization of medium-Mn steel has, up to now, not been fully addressed due to the complexity of their mechanical properties, which are sensitively dependent on their chemical composition and processing conditions. Despite the apparent success in achieving the desired base metal mechanical properties, very few studies have been performed on the effects of fabrication processes, such as welding, forming, etc.

The exploitation of medium-Mn steels is far from mature and the subject is both scientifically and technologically fascinating. In order to provide an overview on the current state-of-the-art of these advanced steels, a Special Issue of Metals is commissioned and we invite contributions covering different aspects of medium-Mn steels.

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 papers will be 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 1000 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.
