Special Issue Information
Dear Colleagues,
The advent of high- and medium-entropy alloys (HEAs and MEAs) has broken through the traditional design methodology of alloys and these have been attracting increasing research attention due to their advanced performance and outstanding properties. Recent progress in compositional and structural design concepts, as well as preparation techniques, has further enhanced the performance of HEAs and MEAs, which is included in the scope of this Special Issue. Owing to excellent strength–ductility tradeoff, fracture toughness at ambient and cryogenic temperatures, high temperature capability, tribological performance, irradiation behavior, corrosion/oxidation resistance, etc., HEAs and MEAs have been considered as promising candidates for future applications in a wide range of industries including aerospace, nuclear, marine, biomedical, energy and mining.
In this Special Issue, we welcome review articles and research papers that focus on the advanced performance of HEAs and MEAs and the innovative design methods that lead to such advanced performance. We also aim to shed light on future research. The topics will include, but are not limited to, (1) the various types of HEAs and MEAs, including 3D transitional, refractory, lightweight, single-phase, precipitation-strengthened, eutectic/eutectoid, gradient and bimodal-grained; (2) the various strengthening and plasticity mechanisms, including twining, phase transformation, dispersed particles, nanostructures, dislocation structures, microbands and cell structures; (3) the various advanced design methods, including high-throughput thermodynamics/kinetics calculation and screening, machine learning, molecular dynamics and density functional theory; (4) the various advanced preparation techniques, including arc-melting, powder metallurgy and additive manufacturing for bulk HEAs and MEAs and jet/plasma spraying for HEA and MEA coatings; and (5) the various advanced characterization tools, including 3D atomic probe tomography and in situ transmission electron microscopy.

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.
