Researchers from North Carolina State University and Duke University have created the first entropy-stabilized alloy that incorporates oxides – and demonstrated conclusively that the crystalline structure of the material can be determined by disorder at the atomic scale rather than chemical bonding.
Schematic illustration of an entropy stabilized oxide at the atomic scale. The grey spheres represent the oxygen sub lattice in the rock salt-structured crystal while the colored spheres represent the metal cations. Each different color corresponds to different elemental species. Note that different metals are distributed randomly. Image credit: Jon-Paul Maria.
