Special Issue Information
Dear Colleagues,
Precipitation strengthening is one of several mechanisms leading to higher strength in metals. This powerful phase transformation is used in many steels to control their properties. These include structural steels, corrosion-resistant steels, heat-resistant steels, as well as tool steels. Precipitation strengthening is normally induced by heat treatment where diverse thermal processes can be applied. Isothermal annealing and quenching with subsequent tempering are the most common heat treatment processes for steels, in which precipitation takes place. Thermomechanical processing is used less often. In special cases, thermal processes are facilitated by physical forces or fields, e.g., the magnetic field.
The chapter on heat treatment deals with deep cryogenic treatment, which benefits mainly steel materials after quenching and tempering. Increases in wear resistance, corrosion resistance, lifetime, and other key properties of steels have been reported in many works.
Despite abundant literature data and available knowledge, research into the above topics remains an enormous challenge for scientists. Refinement of the kinetic description of precipitation, identification of effects of microstructural features, and environmental impacts on precipitation kinetics, the effect of precipitate morphology on the activation energy of defect nucleation, and confirmation of theories of structural changes during deep cryogenic treatment are just a handful of themes to be addressed.
In this Special Issue, we aim to contribute to the entire theory of precipitation in steels to advance the knowledge of heat treatment and deep cryogenic treatment processes. The comprehensive view of the relationships among the treatment process, characterization of fine microstructure, and the final properties of the workpiece should provide another piece in the puzzle.

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.
