Special Issue Information
Dear Colleagues,
Steels are the most widely used metallic materials by human beings currently, the worldwide production was over 1.8 billion tons in 2020, far exceeding the sum of all the other metals. The amazing productivity, low production costs, and low life-cycle carbon emission of steels will ensure their continued extensive use far into the foreseeable future. The commercially available steels possess a very wide range of mechanical properties (e.g., the ultimate tensile strength ranges from 100 to 5500 MPa) arising from their microstructure complexity. The key reason why there are various microstructures in the steel is phase transformation can occur during heat or thermo-mechanical treatments, which is the only metal to play with carbon in diverse phases. The transformation can occur either by breaking all the bonds and rearranging the atoms into an alternative pattern (reconstructive transformation) or by homogeneously deforming the original pattern into a new crystal structure, i.e., displacive or shear transformation. Many essential properties of steels depend on the atomic mechanism of phase change.
Although the steel industry is sometimes seen as a “sunset industry”, the iron and steel science is advancing and there are new technologies for further improvements of the existing and the development of new steels coming. The Special Issue focuses on the phase transformation and novel heat treatment process design of steels, especially those related to the mechanical properties. I am honored to be invited to establish the Special Issue of Metals. Warmly welcome contributions from researchers all over the world. I hope this work will deepen our understanding and promote the progress of the subject.

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.
