Subgrain rotation recrystallization

Subgrain rotation recrystallization (SRR) is a process that occurs in materials, particularly crystalline solids, during thermal or mechanical deformation and annealing. It is a mechanism that leads to microstructural changes in metals and alloys, affecting their mechanical properties. ### Key Aspects of Subgrain Rotation Recrystallization: 1. **Subgrains**: During deformation, grains within a material can become fragmented into smaller regions called subgrains.
