Bulk metallic glass-forming liquids are alloys with typically three to five
metallic components that have a large atomic-size mismatch and a compositi
on close to a deep eutectic. They are dense liquids with small free volumes
and viscosities that are several orders of magnitude higher than in pure m
etals ou previously known alloys. In addition, these melts are energeticall
y closer to the crystalline slate than other metallic melts dire to their h
igh packing density in conjunction with a tendency to develop short-range o
rder. These factors lead to slow crystallization kinetics and high glass-fo
rming ability. Crystallization kinetics is very complex, especially in the
vicinity off the glass transition, dire to the influence of phase separatio
n and the decoupling of the diffusion constants of the different species.
