A Study of Dynamic Recrystallization During Hot Rolling of

Jan 01, 1996 · Dynamic recrystallization in strip &ling:In continuous rod and bar rolling processes, extremely high strain rates and short interpass times are being employed. Typical strains per pass (0.4-0.6) are lower than the critical strain for the onset of dynamic recrystallization at high strain rates. Analysis of Stress-Strain Curves to Predict Dynamic Apr 26, 2021 · Therefore, the onset of dynamic recrystallization and its termination in the microstructure of a material are important in the hot deformation research (Ref 21,22,23,24,25,26). If the processing parameters that affect these microstructural changes can be identified from the high temperature stress-strain curve, it would be very useful for

Dynamic recovery and dynamic recrystallization of NiTi

influence of dynamic recovery and dynamic recrystallization on the hot workability of NiTi alloy [14,15]. In the present work, the dynamic recovery and dynamic recrystallization of NiTi SMA was systematically investigated according to the compression Hot Deformation and Dynamic Recrystallization Behavior Dislocation generation and multiplication are the main hot deformation mechanisms for the alloy. The deformation temperature increaseand the strain rate decrease can promotedynamic recrystallization of the alloy.
