Work hardening, in metallurgy, increase in hardness of a metal induced, deliberately or accidentally, by hammering, rolling, drawing, or other physical processes. Although the first few deformations imposed on metal by such treatment weaken it, its strength is increased by continued deformations.
What are the effects of work hardening?
Work hardening improves tensile strength, yield strength and hardness at the expense of reduced ductility (see Table 1). These effects can only be removed by annealing or normalising.

What is meant by work hardening process?
Work hardening, is the strengthening of a metal by plastic deformation. ... This implies that the metal is becoming stronger as the strain (work) increases. Work hardening is also known as strain hardening or cold working.
