Special Issue Information
Dear Colleagues,
Superalloys are widely used in the aviation, aerospace, and energy industries as key high-temperature structural materials with excellent strength, toughness, fatigue, creep, and microstructure stability. Excellent superalloy properties can not only overcome the design bottlenecks of equipment in high-temperature and high-pressure conditions, extend the service life of core components, and reduce operation and maintenance costs, but they can also provide key material support for the thrust improvement of aerospace propulsion systems and the efficiency optimization of energy equipment. They are also one of the most important metrics to measure the core competitiveness of high-end manufacturing industries and new material industries.
This Special Issue provides an excellent opportunity for the publication of theoretical and experimental studies related to the mechanical properties of Ni-based superalloys. Any new findings about the topic are welcome, such as the influence of processing technology on microstructural evolution and mechanical properties, microstructural evolution and characterization during the hot deformation of wrought superalloys and powder metallurgy superalloys, deformation mechanisms, dynamic recrystallization, related underlying mechanisms, etc. More specifically, this Special Issue will cover, but is not limited to, the following fundamental and applied research topics:
- Ni-based superalloys;
- Forging, rolling, casting, and welding;
- 3D printing and other processing innovations;
- Microstructural evolution and characterization;
- Plastic flow behavior and deformation mechanisms;
- Strain rate and temperature sensitivity;
- Dynamic recrystallization mechanisms;
- Boundary in situ characterization;
- Previous particle boundaries;
- Grain size and refinement;
- Secondary precipitates;
- Texture orientation;
- Dislocation motion;
- Fatigue and fracture.
In keeping with the long-standing tradition of publishing the most recent and highest quality work in Metals, this Special Issue features a collection of manuscripts and is entitled “Mechanical Properties of Ni-Based Superalloys”. This issue features the finest and latest breaking articles in superalloy development from 2025 and is listed with the main indexing services, making the articles readily searchable, available on the web, and citable. Please ensure your paper is submitted by the deadline and thank you for your interest in the “Mechanical Properties of Ni-Based Superalloys” Special Issue of Metals.

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 250 words) can be sent to the Editorial Office for assessment.
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.
