Which heat treatment process is used to remove the changes caused by cold working?
Explanation
Cold working introduces strain and defects in the metal's structure, which can be reversed by annealing. Annealing involves heating the material to a specific temperature and then cooling it slowly, restoring ductility and relieving internal stresses. Other heat treatments like age hardening, homogenization, or solution treatment serve different purposes and do not eliminate the effects of cold work.
