7. Glossary

elastic deformation

Reversible deformation of a material under mechanical stress, mainly due to deformation of atomic or molecular bonds.

plastic deformation

Permanent deformation of a material after mechanical stress, usually accompanied by hardening.

dislocation; dislocation

Linear defect within a crystal; defined by the direction of the defect line and the Burgers vector, it contributes to the plastic deformation of crystals and their work hardening.

strain hardening

Hardening of a crystal during plastic deformation; the multiplication of dislocations beyond the elastic limit leads to numerous interactions between them, making it more difficult for them to move in the sliding planes.
