Work hardening facts for kids
The work hardening, also known as strain hardening, is the strengthening of a metal or polymer by plastic deformation. The plastic deformation of the metals is made 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 (rolling), bending, shearing and drawing.
