Medium-range structure at a length scale between ~0.5 and 3 nm strongly influences the properties and phase transformations of metallic glass alloys. This study aims to characterize such structures through advanced electron diffraction methods, specifically four-dimensional scanning transmission electron microscopy and nanodiffraction techniques. Various structural characterization methods, including fluctuation electron microscopy and angular correlation mapping, were employed to investigate the competition between crystalline and noncrystalline order and to determine the structural motifs that facilitate crystallization and glass formation. Additionally, time-resolved, in situ electron correlation microscopy was utilized to explore spatially heterogeneous dynamics in supercooled liquids and glasses, establishing connections between atomic structure and motion. The results reveal insights into the structural complexity and dynamics of metallic glasses, underlining the challenges of processing and property prediction in these materials. The findings highlight ongoing advancements in characterization techniques, indicating potential for future discoveries in the field.
