WebJan 6, 1998 · Dynamic recrystallization (DRX) and dynamic recovery (DR) are two competing processes by which metals and alloys undergo a reduction in the density of accumulated dislocations during plastic deformation at elevated temperatures. The objective of the present work was to model DRX under isothermal and constant strain rate … Dynamic recrystallization (DRX) is a type of recrystallization process, found within the fields of metallurgy and geology. 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 … See more Geometric dynamic recrystallization occurs in grains with local serrations. Upon deformation, grains undergoing GDRX elongate until the thickness of the grain falls below a threshold (below which the serration … See more Based on the method developed by Poliak and Jonas, a few models are developed in order to describe the critical strain for the onset of DRX as a function of the peak strain of the … See more Discontinuous recrystallization is heterogeneous; there are distinct nucleation and growth stages. It is common in materials with low stacking-fault energy. … See more Continuous dynamic recrystallization is common in materials with high stacking-fault energies. It occurs when low angle grain boundaries … See more • A one-parmenter approach to determining the critical conditions for the initiation of dynamic recrystallization, onset of DRX • Flow Curve Analysis of 17–4 PH Stainless Steel under Hot Compression Test, comprehensive study of DRX See more 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 … christian puls kiel
