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. WebThe metal elements included by the high-entropy alloy are chosen from a group consisted of specific metal elements and by a specific difference of atomic sizes between any two of these metal elements, the high-entropy alloy has the low resistivity, high toughness and high hardness, the high-entropy alloy can be applied to AFM testing probes or other …
