Glass transition

The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or "rubbery" state as the temperature is increased. An amorphous solid that exhibits a glass transition is called a…
