Dynamic recrystallization
WebDynamic recrystallization (DRX) processes are widely used in industrial hot working operations, not only to keep the forming forces low but also to control the microstructure and final properties of the workpiece. According to the second derivative criterion (SDC) by Poliak and Jonas, the onset of DRX can be detected from an inflection point in the strain … WebJan 27, 2024 · There exist 3 styles of dynamic recrystallization [ 19, 20 ]: (1) discontinuous dynamic recrystallization (DDRX), which occurs in alloys with low stacking fault energy by nucleation and growth of new grains; (2) continuous dynamic recrystallization (CDRX), which involves the formation of arrays of low-angle boundaries and a gradual increase in …
