Answer 1

Answer:

to relieve the internal stress

mark me brainliest

Answer 2

Answer:

To relieve the internal stress

Explanation:

Annealing will restore ductility following cold working and hence allow additional processing without cracking. Annealing may also be used to release mechanical stresses induced by grinding, machining etc. hence preventing distortion during subsequent higher temperature heat treatment operations.
