Abstract
Hardening mechanisms in crystalline solids are discussed in terms of dislocation theory. The general features of the two large groups of mechanisms—work hardening caused by the accumulation of dislocations in the material during plastic deformation, and hardening by obstacles present prior to deformation—are emphasized. The latter group is subdivided into defect hardening treated in terms of elastic interactions between dislocations and defects—vacancies, interstitials, impurities, precipitates, etc.—and hardening by short- and long-range order discussed on the basis of replacing energetically preferred types of bonds by preferred types due to the passage of dislocations.
