Special Issue Information
Dear Colleagues,
Heat treatment (including thermo-mechanical and thermo-chemical treatment) is one of the most powerful tools for controlling the mechanical and functional properties of metallic alloys. Although thermal treatment technologies have a long history and traditions, the current society puts forward new challenges and requirements, not only for newly developed steels and non-ferrous alloys but also for resource exploitation, fast and effective production, and limitation of CO2 emissions. Taking into account that most of the energy sources in this sector are mainly based on fossil fuels or heating in electrical resistance furnaces (excluding the salt baths), the heating rates are restricted to the limits of the heat transfer from the heater to the heat-treated part and they do not exceed the ranges of 2 °C/s to 10 °C/s. In recent years, the interest in non-conventional heat treatment processes, where the heating is performed at very high speed via different heating sources, like induction heating or resistive heating by passing the current directly through the sample, is continuously growing. Therefore, these processes are increasingly approaching the stage of industrial technology.
This Special Issue is focused on the results of experiments and modeling related to conventional but also to non-conventional technologies for thermal or thermo-chemical treatments where high heating rates and very short soaking times are used. Alternatively, approaches with multiple thermal treatment steps, like thermal cycling, thermo-chemical treatment, (nano)-composite production, and magnetic materials, are a subject of interest. We encourage researchers to share their experience in this field by publishing their research on applying not only conventional but also innovative technologies like ultra-fast heating, ultra-short annealing, ultra-fast tempering, microwave synthesis, thermal cycling, and thermo-mechanical or thermo-chemical treatment on steels and non-ferrous alloys, showing the link between the processing parameters, microstructure (inclusive texture), and mechanical properties.

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.
