Special Issue Information
Dear Colleagues,
Materials fabricated using mechanical alloying (MA) are making a significant contribution to industrial applications. They represent a highly diverse and strongly multidisciplinary area, with links to numerous industrial sectors, such as aerospace, energy, construction, automotive, transport, packaging, security, and defense. Mechanical alloying was selected as the most appropriate processing method to produce oxide dispersion strengthened (ODS) alloys, which exhibit good creep resistance, thermal stability, wear resistance, oxidation resistance, etc. In recent years, high-entropy alloys (HEAs) have become a new class of metallic alloys which favor the formation of a solid solution instead of intermetallic compounds. Thus, ODS-HEAs are promising structural materials for high-temperature and radiation resistance applications due to high configurational entropy and the pinning effect of dispersed oxide particles, which restrict dislocation motion and restrain the growth of grains. This Special Issue aims to present the recent developments in high-entropy alloys synthesized by mechanical alloying. Also, it focuses on the effects of oxide dispersoids on the properties of HEAs for elevated temperature applications.
In particular, the topics of interest for this Special Issue include, but are not limited to, the following:
- High-entropy superalloy;
- Eutectic high-entropy alloy;
- Refectory high-entropy alloy;
- Lightweight high-entropy alloy;
- ODS high-entropy alloy.

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.
