Special Issue Information

Dear Colleagues,

Increasing technological demand in several industries has encouraged the development of alloys that perform at a higher level than conventional alloys. Some of the properties that high-performance alloys exhibit include high strength or toughness, alloys resistant to creep, corrosion, or fatigue, alloys capable of operating in high-temperature and cryogenic environments, and thermoelectric properties. The processing of high-performance alloys is also of great importance in this field of study, including fabrication procedures, thermomechanical treatment, and joining techniques. Through the investigation of properties and processing, the application of high-performance alloys in aerospace, energy generation, cryogenics, and many other industries can flourish.

In this Special Issue, we invite researchers to submit articles that focus on the advances in high-performance alloy processing techniques, characterization of their unique properties, and discussion of novel high-performance alloy applications.

Topics addressed in this Special Issue may include, but are not limited to:

  • Material properties;
  • Metallurgical characterization;
  • Joining techniques;
  • Industrial applications;
  • Computational modeling;
  • Thermomechanical treatments;
  • Additive manufacturing techniques;
  • Thermoelectric alloys;
  • High/medium entropy alloys.

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.

There is little doubt that there is significant potential for high-entropy alloys (HEAs) in cryogenic and aerospace applications. However, given the immense design space for HEAs, there is much more to be explored. This review will focus on four areas of application for HEAs that receive less attention. These focus areas include joining technologies, HEA nanomaterial synthesis, catalysis, and marine applications. The performance of HEAs as a filler metal for welding and brazing as well as their performance as a welded/brazed base metal will be discussed. Various methods for synthesizing HEA nanomaterials are reviewed with specifically highlighted applications in catalysis and energy storage. HEA catalysts, in particular, will be discussed in detail regarding their effectiveness, selectiveness, and stability. Marine applications are explored given the inherent corrosion resistance of HEAs as well as superior antifouling properties that make HEAs an intriguing marine-ready material. Full article
