1. Hot forging: a forging process performed above the metal recrystallization temperature.
2. Hot rolling: a rolling process carried out at a temperature higher than the recrystallization temperature.
3. Cold rolling: a rolling process in which the plastic deformation temperature is lower than the recovery temperature.
4. Annealing: A metal heat treatment process that slowly heats the metal to a specific temperature, maintains it for a sufficient time, and then cools it at an appropriate speed (usually slow cooling, sometimes controlled cooling).
5. Pickling: Immerse the parts in an aqueous solution such as sulfuric acid to remove oxide and other films on the metal surface of the titanium plate. It is the pre-treatment or intermediate treatment for electroplating, enamel, rolling and other processes.
