Web13 de mar. de 2024 · Abstract It has been shown that oxide ceramics containing multiple transition and/or rare-earth elements in equimolar ratios have a strong tendency to crystallize in simple single-phase structures, stabilized by the high configurational entropy. In analogy to the metallic alloy systems, these oxides are denoted high-entropy oxides …
WebThe high entropy effect stabilises multi-component carbide phases and forms compositions that might otherwise not be stable. After several years of investigation of HECs, several methods of synthesising HECs have been developed. The microstructures and properties of HECs have been studied and compared with traditional carbides.
