dynamic recrystallization
Dynamic Recrystallization is defined as a process occurring during the hot plastic deformation of metals, whereby new grains are formed to replace the deformed ones. This is something that enhances material properties like toughness and ductility.
Key Features:
- Grain Refinement: These newly formed, strain-free grains replace deformed grains, leading to better uniformity and strength.
- Occurs During Deformation: Occurs at high temperature and during the working of metals. The continuous strain results in recrystallization.
- Improved Mechanical Properties: Increased ductility and toughness, and decreased work hardening, resulting in an easier process for forming metals.
The essence of Dynamic Recrystallization is in refining grain structure, partly during metal processing. Thus, it bears an essential role in metals workability and performance. Theoretical developments in metal forming techniques have been thus exploited in order to improve Dynamic Recrystallization with regard to material quality.
