Special Issue Information
Dear Colleagues,
At high temperatures, heat-resistant alloys (superalloys) maintain their microstructural stability while also exhibiting excellent creep resistance, high oxidation/corrosion resistance, high strength, and low thermal expansion. Heat-resistant alloys/superalloys are widely employed in gas and steam turbines (disks, combustion chambers, bolts, casings, shafts, exhaust systems, cases, blades, vanes, burner cans, afterburners, thrust reversers), metal processing (hot-work tools and dies, casting dies). In addition, they are used in nuclear power systems, coal gasification and liquefaction systems, heat-treating equipment, chemical process industries, and in other specialized applications requiring heat and/or corrosion resistance. The popular superalloys consist of nickel, iron–nickel, and cobalt alloys. For a materials scientist, one of the most difficult challenges is to develop new materials for use in high-temperature applications. High melting point, excellent oxidation/corrosion resistance, high-temperature performance (high strength), microstructural stability at high temperatures, low density, high stiffness, low cost, reliable performance, and easy to process are the research targets when designing heat-resistant alloys (superalloys). The production methods of the superalloy’s component are also an essential consideration when choosing and designing these alloys.
Many research issues still persist despite extensive research and development efforts, such as improving material properties and manufacturing process optimization. In this Special Issue, we aim to publish a wide scope of articles on various aspects of heat-resistant alloys/superalloys. The potential scope of interest includes (but is not limited to):
- Heat-resistant alloys/superalloys design;
- Ni-based/ Co-based/ Ti- alloys;
- Al-based heat-resistant alloys;
- Metal matrix heat-resistant composites;
- Effect of rare earth elements on heat-resistant alloys;
- Processing technology (additive manufacturing, casting process, powder metallurgy, forming);
- High-temperature mechanical properties;
- Microstructure evaluations of heat resistant/superalloys alloys;
- Oxidation/corrosion properties;
- Simulation and modeling.

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. Materials is an international peer-reviewed open access semimonthly 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.
