Question

Plastic deformation of metal below its recrystallization temperature is called

• A. Cold working
• B. Hot working
• C. Deep drawing
• D. Tempering

Hint:

Cold working is used to shape and strengthen materials, but it can also cause residual stresses and reduced ductility if not followed by annealing.

Answer 1

The Correct Option is A

Cold working involves the plastic deformation of metals at temperatures below their recrystallization temperature, leading to hardening and strengthening of the material.
