Special Issue Information

Dear Colleagues,

Ultra-high manganese steels containing 15–25 weight % Mn and with additions of Si and Al of ~2–4 weight % are characterized by a high-strength–high-ductility combination, excellent formability, and superior fracture toughness because of TRIP (transformation-induced plasticity) or TWIP (twinning-induced plasticity) effects. Fe-C-Mn alloys have relatively low stacking fault energy. The addition of Al and Si elements to the Fe–Mn alloys impacts their stacking fault energy and phase stability, leading to variable mechanical properties that are governed by the extent of deformation twinning and strain-induced martensitic transformation, namely, γ(fcc)→ε(hcp) and γ(fcc)→α(bct). Recent studies have indicated that the Fe–Mn–Al–Si alloy primarily exhibits a TRIP effect when the manganese content is less than 15 weight %, while the TWIP effect is dominant when manganese content is higher than 25 weight %. However, when the manganese content is 15–25 weight %, the TRIP and TWIP effects coexist. TRIP/TWIP steels are effective candidates for automotive sheet because they can reduce the weight of the automotive components, improve fuel efficiency, reduce emission, and enhance the degree of safety.

The Special Issue will include articles reporting new and progressive research results in the areas of medium Mn and high Mn steels, as well as reviews of particular classes of fundamental physics of the materials and their applications. Manuscripts will be welcomed from both fundamental scientific researchers and authors belonging to industrial companies involved in the field.

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 2000 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.
