In the field of metallic glasses, 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 ideal glass state. Using this HE-MGs, we studied the various characteristics of ideal glasses. The results contributed us to enhance the insight of ideal glass state in terms of structural characteristics, mechanical property, and abnormal crystallization behavior based on the experimental evidence.
