Special Issue Information
Dear Colleagues,
Ni-based superalloys stand as core materials in strategic sectors like aerospace and energy, owing to their exceptional high-temperature strength, creep resistance, and corrosion resistance—traits that make them indispensable for critical components such as aero engine turbine blades and nuclear reactor parts. Innovations in their forming processes, precise control of microstructures, and breakthroughs in comprehensive properties are not only technical priorities but also key drivers for upgrading high-end manufacturing and supporting industrial advancement.
While traditional manufacturing processes (e.g., conventional casting) face limitations in precision and performance uniformity, there have been rapid breakthroughs in advanced technologies including precision casting, additive manufacturing (e.g., SLM, EBM), and powder metallurgy, enabling more flexible fabrication of complex components and enhanced material consistency. Notably, the precise regulation of microstructures—such as the size, distribution of γ' phases and the state of grain boundary phases—directly dictates the alloys’ service life and reliability under harsh conditions. Meanwhile, improving comprehensive properties must align with the demands of extreme service environments, from high-temperature oxidation to radiation exposure.
For this Special Issue, we kindly invite submissions focusing on four key areas: 1. development of advanced forming processes; 2. mechanisms of microstructure control; 3. optimization of comprehensive properties; and 4. process–microstructure–property correlation models. We particularly welcome innovative research featuring "low energy consumption, low cost, and high performance," as well as articles on technological breakthroughs tailored to specific application scenarios. The aim of this initiative is to facilitate academic exchange, accelerate technology translation, and boost academic innovation and industrial collaboration in the field of Ni-based superalloys.

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.
