Metallic glasses exhibit a unique combination of structural and functional properties, including exceptional strength, making them among the most remarkable classes of engineering materials. This webinar explores recent advances in understanding the structure and dynamics of metallic glasses, highlighting how emerging experimental techniques, theoretical frameworks, and computational models are providing unprecedented insight into atomically disordered solids. Speakers will discuss new perspectives on medium-range order, network formation, and structural heterogeneity, as well as how these features influence material behavior and properties. The session will examine how these developments are helping to establish predictive structure-property relationships and improve our understanding of phenomena such as relaxation, rejuvenation, creep, and other dynamic processes in glassy materials. This webinar is presented in conjunction with the August 2026 issue of MRS Bulletin.
