Abstract

Disorder is both intrinsic to all materials and a route to enhanced functionality. A combination of 1) high chemical disorder and 2) metal-nonmetal bonding offers a new direction for thermal protection barriers, wear- and corrosion-resistant coatings, batteries, and catalysts. Engineering these materials for applications demands an understanding of the mechanisms governing synthesizability and other entropy-driven behavior, a challenging task often resolved within a limited context or neglected altogether. A simple modeling paradigm is presented that has already led to the discovery of new metal-carbide systems achieving high hardness values as predicted. Promising new research directions for high-entropy ceramics will also be identified.
