百科解釋
Dynamic recrystallization (DRX) is a type of recrystallization process, found within the field of metallurgy. In dynamic recrystallization, as opposed to static recrystallization, the nucleation and growth of new grains occurs during deformation rather than afterwards as part of a separate heat treatment.
