The most attractive material properties and performance among glassy alloys are derived from microstructures based upon a high number density of nanocrystals dispersed within an amorphous matrix. The generation mechanism of these nanocrystal dispersions is still not clear; the present analyses point out that a nearly balanced kinetic competition between crystallization and vitrification is essential but indicate also the involvement of further mechanisms.
