The as-spun specimen maintains its amorphous structure with a relatively large size of nanoscale defects. However, crystallization is observed for the CT MG with a high concentration of nanoscale defects that decreases during the crystallization process. The crystallization develops readily in the CT MG due to the greater size of the ordered clusters, the higher concentration of seeding sites, and its greater nucleation rate.
