Fundamental Understanding and Applications of High-Entropy Alloys
Issue Date: October 2018 
Submission Deadline: March 1, 2018

As an emerging field, research on high-entropy alloys now has attracted rising worldwide attention and interest from both academia and industry since 2004. The number of published papers increases rapidly each year, and there have been many dedicated conference symposia and workshops on high entropy alloys. Traditional physical metallurgy principles as well as novel processing methods have all been applied to high entropy alloys, and new materials with extraordinary properties have been reported. The high-entropy concept has been extended to ceramics, semiconductors, polymers, superconducting materials, etc. As a result, the field has advanced dynamically and rapidly in almost every aspect of materials science. This JMR Focus Issue will provide readers up-to-date information on high-entropy alloys regarding their fundamentals (e.g., formation, thermodynamics, kinetics, structures, defects, mechanical properties, functional properties, environmental properties) and applications (e.g., structural materials, coatings, nuclear materials, high-temperature materials).

Contributed papers are solicited in the following areas:
• Thermodynamics: Phase diagrams, phase transformations (e.g., at high temperature and/or high pressure), thermochemistry measurements
• Kinetics: Diffusivities, high throughput diffusion multiples
• Computational modeling: First-principles, molecular dynamics, Monte Carlo, phase field, finite element methods, CALPHAD, continuum, empirical parameters, machining learning
• Defects: Vacancies, dislocations, stacking faults, twinning, grain boundaries, interfaces, surfaces
• Processing: Homogenization, additive manufacturing, rapid solidification, grain refinement, powder metallurgy
• Microstructure characterization: Neutron, synchrotron and x-ray scattering, transmission electron microscopy (TEM), high-resolution TEM, in situ TEM, atom-probe tomography
• Mechanical properties: Elasticity, plasticity, fracture, wear, creep, fatigue, high strain rate, nanoindentation
• Environmental properties: Corrosion, oxidation, irradiation
• Other high-entropy materials, such as oxides, carbides, borides, polymers, compounds

Manuscript Submission

To be considered for this issue, new and previously unpublished results significant to the development of this field should be presented. The manuscripts must be submitted via the JMR electronic submission system by March 1, 2018. Manuscripts submitted after this deadline will not be considered for the issue due to time constraints on the review process. Please select “Focus issue: Fundamental Understanding and Applications of High-Entropy Alloys” as the manuscript type. Note our manuscript submission minimum length of 6000 words, with a maximum of 6-8 figures. Review articles must be pre-approved by proposal to the Editor-in-Chief. The proposal form and author instructions may be found at www.mrs.org/jmr-instructions. All manuscripts will be reviewed in a normal but expedited fashion. Papers submitted by the deadline and subsequently accepted will be published in the Focus Issue. Other manuscripts that are acceptable but cannot be included in the issue will be scheduled for publication in a subsequent issue of JMR.
