A variety of families of bulk metallic glasses, such as Vitreloy 1 and Pd-P-base BMGs, exhibit a two-stage, sequential nano-crystallization upon heating above their glass transition temperatures. This commonality suggests a potential connection between glass-formation ability and nanoscale crystallization. To better understand this relationship, we have investigated the kinetics of nanoscale crystallization in Zr-based bulk metallic glasses at multiple length scales using neutron and synchrotron X-ray scattering, complemented by microscopic studies. The role of diffusion and chemical interactions in determining the crystallization pathway will be discussed, and its implications for understanding the glass-forming ability will be presented. Our findings may provide useful insights for developing bulkier metallic glasses.
