Scope One main objective of this high-entropy materials (HEM) symposium is to connect the high entropy alloys (HEAs) or the more broadly-defined multi-principal-element alloys (MPEAs) community that started off with two journal papers published in 2004 and the conventional materials community that has already created a huge number of multi-component compounds (Oxides, Borides, Carbides, Silicides, intermetallics, and others) in the past several decades. Many conventional multi-component materials identified prior to 2004 may still satisfy the definitions of HEAs or MPEAs but may be missed during literature searches using the keywords of HEAs or MPEAs. Bringing these two communities together will benefit both by filling the gap and also avoiding repeating research into known materials.

Another objective is to promote the design and development of high-performance materials for industrial applications using the high entropy concept. It is recognized that configurational entropy does not always dominate materials properties, and efficient and reliable methods are urgently needed to accelerate discovery of new cost-effective materials for wide arrays of industrial applications. As such this HEM symposium solicits recent quality research on fundamental understanding and applications of HEAs, MPEAs, and conventional multi-component materials including solid solution alloys, alloy compounds, composites, ceramics, semiconductors, polymers, and many other functional materials.

Topics of interest include but not limited to:
(1). Combinatorial synthesis methods in bulk and thin film forms
(2). High throughput characterization of the phases, microstructures and properties
(3). Advanced characterization such as neutron scattering and atom probe tomography
(4). Physical properties such as electric/ionic/thermal conductivities
(5). Functional (e.g., magnetic, magnetocaloric, thermoelectric, superconducting, dielectric, optical) properties.
(6). Thermodynamic and kinetic properties
(7). Mechanical properties (e.g., elasticity, strength, hardness, ductility, toughness, creep, fatigue)
(8). Environmental properties (e.g., aqueous corrosion, oxidation, irradiation, hydrogen storage, cryogenic temperatures, high temperatures, high pressure)
(9). Theoretical modeling and simulation using density functional theory, molecular dynamics, dislocation theory and dynamics, Monte Carlo, phase-field, finite elements, and CALPHAD.
