Abstract: Entropy represents the degree of chaos in a system, and in high-entropy materials it originates from the configuration entropy when a solid solution is formed. Highentropy actually signifies the presence of many elements with a roughly even composition. Adding complex components to traditional structurally disordered glass creates a high-entropy glass, which leads to changes in its structure and properties. The emergence of high-entropy glass has transcended the traditional single element design concept, and the flexibility of element replacement has greatly broadened the scope of material innovation. After 20 years of development, not have only a large number of high-entropy glass materials been discovered, but also new structures and new phenomena have emerged, giving birth to new methods of using entropy to control the properties of glass. Starting from several typical cases, this paper reviews the progress in the development of high-entropy glass with regard to material design, structural characteristics, dynamic phenomena, performance regulation, etc., and describes the opportunities for high-entropy metallic glass.
