Amorphous supercooling ability

K/s (Inoue et al. 1991 a) for Mg-Cu-Y alloys containing 65-80 at% Mg, based on the experimental data as well as the direct Unite difference method. It is therefore concluded that Mg-based amorphous alloys have an extremely large glass-forming ability due to the high resistance of the supercooled liquid against crystallization. 

The particles can then break out of their positions in crystalline solids, which have definite melting points. In contrast, amorphous solids, such as glass and plastics, have no definite melting point. They have the ability to flow over a range of temperatures. Therefore, amorphous solids are sometimes classified as supercooled liquids, which are substances that retain certain liquid properties even at temperatures at which they appear to be solid. These properties exist because the particles in amorphous solids are arranged randomly, much like the particles in a liquid. Unlike the particles in a true liquid, however, the particles in amorphous solids are not constantly changing their positions.
