How can a dislocation be cured?

Dislocations can be cured by a number of methods, including annealing, quenching, and plastic deformation.

Annealing is the process of heating a metal to a temperature at which the dislocations become mobile and can move out of the crystal. This can be done by heating the metal in a furnace, or by using an electric current.

Quenching is the process of rapidly cooling a metal from a high temperature, which can trap dislocations in the crystal. This can be done by immersing the metal in water or oil, or by using a stream of cold air.

Plastic deformation is the process of applying a force to a metal that causes it to deform, which can also move dislocations out of the crystal. This can be done by rolling, forging, or extruding the metal.
