Special Issue Information
Dear Colleagues,
The advanced structural/high-strength steels with low-to-medium carbon content and additions of Cr, Ni, Mn, Mo, W, V, Nb, N and other elements are the main structural material used in different industrial fields due to their good mechanical properties, machinability, and low cost. These steels are characterized by the complex microstructures with high densities of internal interfaces, carbides/carbonitrides, and free dislocations. The improved strength of these steels is based on a combination of the different strengthening mechanisms, i.e., solution hardening and precipitation hardening grain boundary strengthening, and depends significantly on the microstructural characteristics. The microstructural evolution and methods to improve the strength–ductility balance of these steels are of great interest, and many studies have been performed in this area during the last decade. However, further investigations are required to clarify the microstructure–mechanical properties relationship and to determine a more reliable alloying design.
The aim of this Special Issue is to clarify the basic principles of alloying design, processing and applications, as well as new progress and findings, in the field of structural/high-strength steels. The articles presented in this Special Issue will cover various topics, including but not limited to:
Alloying design;
Microstructure characterization;
Mechanical behaviour at elevated temperatures;
Heat treatment and thermo-mechanical processing;
Microstructural degradation and fracture behaviour;
Precipitation and coarsening of secondary particles;
Corrosion, physical and mechanical behaviours;
Welding of the similar and dissimilar materials;
Microstructure–mechanical properties relationship.

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. Crystals 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 2100 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.
