Deformation of High Entropy Alloys under Extreme Conditions

Dear Colleagues,

As a novel class of materials, high-entropy alloys (HEAs) usually exhibit excellent mechanical properties, being significantly promising for structural applications. As partially related to the high compositional complexity and configurational entropy, HEAs process much more metastable states compared with conventional dilute alloys, and thus, broader tailorable mechanical properties are available. In particular, under extreme conditions, outstanding resistances and large tolerances to external sufferings can be realized in HEAs. For instance, the highest fracture toughness of engineering materials under cryogenic temperatures has been found in face-centered cubic (FCC) HEAs, due to the active deformation twinning behavior associated with the very low stacking fault energy. Therefore, understanding the fundamentals of the outstanding performance of HEAs under extreme conditions is critical for the further alloy development, production, and application.

It is our pleasure to invite you to submit a manuscript to this Special Issue, which will focus on the deformation of HEAs under extreme conditions, including low/high temperatures, high-speed loading, irradiation, corrosion, wear, high pressure, hypergravity. But it is not limited to the above topics. The scope will cover fundamental research and all other aspects of alloy development, synthesis, heat treatment, component manufacturing, computer simulation and engineering application are also considered.

Submissions of communications, full papers, and reviews are all welcome.

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.
