Abstract Scope |
In the field of metallic glasses, the ideal glass state has attracted special attention because it is expected to have the characteristic of high mechanical strength based on its unique atomic structure. The unique structure is characterized by high diversity in local structure, which means that it is not dominated by particular motifs. Even though it is suggested that mixing a large number of elements with different atomic sizes is a way to design ideal glass, there is a lack of research on analyzing the ideal glass experimentally. In this study, we designed high entropy metallic glasses (HE-MGs) with 10 different elements to make the atomic structure close to the ideal glass state. Using these HE-MGs, we studied the various characteristics of ideal glasses. We expect that the results enhance the insight of the ideal glass state in terms of atomic structural characteristics, unique mechanical properties, and abnormal crystallization behaviors. |
