of a hot working operation. Sometimes this process is performed simultaneously
with the homogenization process.

furnace by rapid heating; if necessary, it may dwell shortly at the appropriate
temperature.
3.4.7

recrystallization temperature, kept warm for a certain period of time and then cooled,
to recrystallize the workpiece, thereby eliminating the work hardening.

Annealing treatment, which is performed on the heat-treated alloy products, through
precipitation or coarsening of the precipitation strengthening phase, to obtain ideal
properties such as plasticity and corrosion resistance.
3.4.19
Aging
Heat treatment, in which the alloy workpiece is subject to solid solution treatment,
after being quenched at high temperature or deformed by cold working to a certain
extent, it is placed at a higher temperature or room temperature, to maintain its shape

3.4.24
Artificial aging
A heat treatment, that strengthens the alloy through rapid de-solvation of soluble
components in a supersaturated solid solution, above room temperature.
3.4.25
Delayed aging
A process that keeps the temperature of the alloy below room temperature, thereby
delaying its natural aging. When returned to room temperature, aging continues
normally.
3.4.26
Peak aging
Artificial aging, which is carried out at a certain temperature or time, to achieve
maximum hardening of the alloy.
3.4.27
Under-ageing
Artificial aging, which is carried out at a temperature or time lower than peak aging,
resulting in a slight decrease in strength and an increase in elongation, as compared
to peak aging.
3.4.28
Over-ageing
Artificial aging, which is carried out at a temperature or time higher than peak aging,
to improve the performance matching of the alloy, such as resistance to stress
corrosion or intergranular corrosion; compared with peak aging, the strength of the
alloy decreases.
