Recrystallization Basics
• Recrystallization is essential to thermomechanical
processing of metallic materials. Plastic
deformation stores energy in the form of
dislocations and also distorts the shape of the
grains. Recrystallization restores the material to
an undeformed state.
• Static recrystallization occurs on heating the
deformed material to an elevated temperature.
• Dynamic recrystallization occurs during the
plastic deformation. This only occurs for hot
deformation at temperatures greater than 0.5 of the
melting point.
