ABSTRACT
A solid alloy with a liquid-like (noncrystalline) atomic arrangement is called a metallic glass or an amorphous (metallic) alloy. A glass is obtained when a liquid is cooled to a state of rigidity without crystallizing; such an alloy will exhibit a glass transition temperature. On the other hand, if a material with a similar structure is made by some processes other than cooling from the liquid state, then it is called an amorphous alloy.
