metalli omaduste muutumine (tugevuse ja kõvaduse suurenemine ning plastsuse ja sitkuse vähenemine) külma plastse deformeerimise protsessi/operatsiooni tulemusena, strengthening (increase in strength and hardness, ie resistance to plastic deformation) produced by plastic deformation, This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material. Work-hardened structure can be removed by recrystallization heat treatment. (see: dislocation, recrystallization annealing/recrystallizing)
