During cold working process
A. Grain structure is distorted
B. Strength and hardness of metal increases
C. Close dimensional tolerance can be maintained
D. All of the above
Answer: Option D
Solution (By Examveda Team)
Cold working is the plastic deformation of metals below the recrystallization temperature. In most cases, such cold forming is done at room temperature. The major cold-working operations can be classified basically as squeezing, bending, shearing and drawing.This Question Belongs to Mechanical Engineering >> Workshop Technology
