In crystals, ductility and tensile strength are opposite-parity sigmoidal functions of the temperature at which this occurs, because the resulting grain size is proportional to its temperature.
FCC lattices generally display the type of twinning named for this process. In a glass, the condition by this name corresponds to a viscosity of ten to the 13 poise and is the standard point between the strain and softening points. In crystals, ductility and tensile strength are opposite-parity sigmoidal functions of the temperature at which this occurs, because the resulting grain size is proportional to its temperature. The three regimes of this procedure are recovery, grain growth, and recrystallization; the so-called cold-work regime lies below it. For 10 points, give this term for a heat treatment designed to change the microstructure of a material, often by removing built-up stresses.
