Glass transition of amorphous alloys

When the crystallization of liquid alloys can be prevented during cooling, glass or amorphous alloys are formed. A glass transition is a phase transition between a liquid and a glass, which 

A specimen in mass of 10 mg is placed in the sample holder. A constant flow of argon gas is used to prevent the oxidation of the specimen. 

The specimen is heated to - 100 K at a heating rate of 40 Kmin , then cooled to ambient temperature with heating at (p = 200 K min
