Luo, S., Khong, J. C., Huang, S., Yang, G., & Mi, J. (2024). Revealing in situ stress-induced short- and medium-range atomic structure evolution in a multicomponent metallic glassy alloy. Acta Materialia, 272, Article 119917. https://doi.org/10.1016/j.actamat.2024.119917

Deformation behaviour of multicomponent metallic glasses are determined by the evolution/reconfiguration of the short- and medium-range order (SRO and MRO) atomic structures. A precise understanding of how different atom species rearrange themselves...
