Special Issue Information
Dear Colleagues,
Nickel-based superalloys are the cornerstone materials for high-temperature applications, particularly in the aerospace and energy sectors, owing to their exceptional mechanical strength, creep resistance, and microstructural stability under extreme conditions. The continuous drive for enhanced efficiency and performance necessitates a deeper understanding of the intricate relationships between processing, microstructure, and properties in these advanced alloys.
This Special Issue aims to compile cutting-edge research and comprehensive reviews that address the fundamental and applied aspects of nickel-based superalloys. We welcome original contributions and state-of-the-art reviews that explore, but are not limited to, the following topics:
- Microstructural Evolution: Advanced characterization (e.g., via SEM, TEM, APT, synchrotron techniques) of γ/γ' phases, topologically close-packed (TCP) phases, carbides, and grain boundaries. Studies on microstructural stability during long-term aging or service.
- Mechanical Behavior: Investigations into deformation mechanisms, creep, fatigue (low-cycle and high-cycle), fracture toughness, and environmental degradation (oxidation, hot corrosion) from room temperature to ultra-high temperatures.
- Processing-Microstructure-Property Relationships: Research linking novel processing routes (additive manufacturing, powder metallurgy, advanced heat treatments) to resultant microstructures and mechanical performance.
- Alloy Design and Development: Experimental and computational (e.g., CALPHAD, phase-field, DFT) studies focused on designing new alloys or coatings with optimized properties.
- Modeling and Simulation: Multi-scale modeling efforts dedicated to predicting microstructural evolution or mechanical response under complex thermo-mechanical loading.
This collection seeks to provide a platform for sharing insights that will propel the development of next-generation superalloys for future technological challenges. Researchers are cordially invited to submit their manuscripts.

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.
