Q136
The cold working of metals is carried out
A.
At the recrystallisation temperature
B.
Below the recrystallisation temperature
AnswerC.
Above the recrystallisation temperature
D.
At any temperature
Answer: Option B
Solution
Answer: Option B
Solution:
Cold Working: Plastic deformation of metals below the recrystallization temperature is known as cold working. It is generally performed at room temperature.
In some cases, slightly elevated temperatures may be used to provide increased ductility and reduced strength.
