Special Issue Information

Dear Colleagues,

In recent years, significant research progress has been made in the development and characterization of high entropy materials, such as transition metal-based high entropy alloys, refractory high entropy alloys, high entropy carbides films, high entropy nitrides films, high entropy oxides, and more recently, high entropy bulk ceramics of carbides, borides, nitrides, and silicides. High entropy materials have opened up possibilities for new compositions due to the developments in thermodynamic modeling and fabrication techniques based on conventional routes, such as arc melting, powder metallurgy, physical vapor deposition, thermal spray, and additive manufacturing. The superior properties of the high entropy materials are pushing the boundaries of conventional materials. This Special Issue on High Entropy Materials, bulk and coatings is aimed towards gathering recent research findings from different researchers to understand new insights and properties arising from different fabrication routes, so that the material science of high entropy materials can be accelerated towards the applications of these new materials. In this Special Issue, specific topics of interest include high entropy alloys/ceramics/composites, bulk and coatings, for applications such as structural, tribology at room and high temperature, aerospace, radiation resistance, oxidation and corrosion resistance, and more.

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. Entropy 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.

In this work, the formation of carbide with the concertation of carbon at 0.1 at.% in refractory high-entropy alloy (RHEA) Mo15Nb20Re15Ta30W20 was studied under both ambient and high-pressure high-temperature conditions. The x-ray diffraction of dilute carbon (C)-doped RHEA under ambient pressure showed that the phases and lattice constant of RHEA were not influenced by the addition of 0.1 at.% C. In contrast, C-doped RHEA showed unexpected phase formation and transformation under combined high-pressure and high-temperature conditions by resistively employing the heated diamond anvil cell (DAC) technique. The new FCC_L12 phase appeared at 6 GPa and 809 °C and preserved the ambient temperature and pressure. High-pressure and high-temperature promoted the formation of carbides Ta3C and Nb3C, which are stable and may further improve the mechanical performance of the dilute C-doped alloy Mo15Nb20Re15Ta30W20.
