Recrystallization temperatures are generally a bit lower than homogenization temperatures because there is no macroscopic diffusion required, as opposed to the homogenization process. They also depend on the cold-working: the more important the cold-working, the lower the recrystallization temperature.

The amount of fine particles blocking recrystallization can be controlled by … The recrystallization temperature of Alloy A is found to be about 200K higher than that of AA2618. The grains of the Alloy A containing scandium and zirconium were refined. 2018-4-24 · For commercial-purity aluminum and commercial alloys, however, normal variations in composition have little effect on recrystallization behavior. Extensively cold worked commercial alloys usually can be recrystallized by heating for several hours at 650 to 775°F (340 to 410°C). … 1994-10-6 · The logarithmic maximum stress and reciprocal temperature relationship is non-linear in the temperature range 200–500°C which indicates a complex mechanism. Transmission electron microscopy confirms that the dislocation densityis increased and subgrain size is decreased with an increase in strain rate and decrease of the test temperature.

In other cases, suppression of recrystallization is desired 2021-4-13 · Fig. 7.33 illustrates that as aluminium content decreases in copper, the value of n increases from 0.1 to higher values and almost becomes 0.5 when the temperature is 600°C. The solute atoms (of impurities as well as alloying elements) is solid solution state are elastically attracted towards dislocations to form Cottrell atmospheres, and towards the grain boundaries to form grain-boundary-atmospheres.

For commercial-purity aluminum and commercial alloys, however, normal variations in composition have little effect on recrystallization behavior. Extensively cold worked commercial alloys usually can be recrystallized by heating for several hours at 650 to 775°F (340 to 410°C). Grain size is also strongly affected by composition.

After heating and a short soaking time the components are cooled freely in air (gas). The patterns in which atoms are arranged in the solid state determine properties. These arrangements can be manipulated by altering parameters such as the chemical composition, temperature and magnetic field.
