Special Issue Information

Dear Colleagues,

Due to their excellent resistance to mechanical and chemical degradation, poly- and single-crystal superalloys are high temperature materials used in gas-turbine engines. The number of alloying elements in these alloys is usually greater than ten, and each element has a specific function for improving properties. Therefore, the composition design, on one hand, is always one critical aspect in developing the promising superalloys, which can perform excellently when serving at elevated temperatures. On the other hand, a long time service under harsh conditions, such as high temperature, high pressure, corrosive environment, and applied stress, could lead to damage in superalloys, which will result in the failure of component. Thus, the damage mechanisms of crystal superalloys is another key aspect.

The composition changes in designing the superalloys could lead to variations in the microstructure characterizations, such as the morphology, element distribution, phase constituents, etc., which will determine the performance and change damage modes of the alloys. Hence, the relationships among “composition design–microstructure characterization–damage mechanism” are interesting for the development of new superalloys with excellent performances.

In this Special Issue, we welcome articles that focus on the composition design and damage mechanism of crystal superalloys. Papers on material preparation methods, alloy and component behaviour, and final products’ performance are also encouraged.

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.
