Abstract Scope Attributed to their unique mechanical and functional properties, nanocrystalline marginal metallic glass composites have attracted extensive research interest over the past years. Partial devitrification of the Al and Fe-RE (RE: rare-earth element) marginal metallic glasses results in anomalous nucleation rate of nanocrystals conflicting with the classical nucleation theory by several orders of magnitude. We’ve been working on revealing the root cause of nanocrystal formation through partial devitrification of metallic glasses for more than a decade. In this talk, we will talk about our long-term experimental and computational progress regarding synchrotron-based high energy X-ray diffraction (HEXRD), fluctuation and conventional electron microscopy, atom probe tomography (APT), and molecular dynamics (MD) studies on as-quenched, devitrified, and molten Al-RE based metallic glasses.
