Recrystallization/precipitation behaviour in microalloyed steels

Recrystallization, Precipitation Behaviors, and Refinement of Austenite Grains in High Mn, High Nb Steel

“…Obviously, stress relaxation curve can reflect recrystallization softening and precipitation hardening behavior effectively through the change in curve's slope. [12][13][14] In general, once the static recrystallization starts, the curve's slope will increase, namely, the softening of material gets accelerated by recrystallization. However, it is interesting to observe that for stress relaxation curve of 0.1Nb steel at 1273 K (1000°C), no expected accelerated softening by recrystallization occurs, as well as no suppressed softening by precipitation.…”

Recrystallization and strain accumulation behaviors of high Nb-bearing line pipe steel in plate and strip rolling

“…Stress relaxation method [9,10] can supply enough data to analyze the whole softening behavior in a discretional given condition. It can be used to characterize the recovery or recrystallization behaviors, and evaluate the effect of solute dragging and precipitate pinning.…”

Effect of Nb Addition on the Hot Deformation Behavior and Microstructure of Low Carbon Steel

“…The effect of static and dynamic recrystallization on the rolling load has been investigated using a strip rolling simulation model which indicated the importance of controlling the interpass times during different hot rolling stages. Kliber et al and Aranas et al have found, using simulation and modeling of the hot deformation process, that the interpass times are related to the mean flow stresses (MFS) at each rolling stand and are demonstrated to lower the shorter interpass times [7,8]. The mean flow stress values can be directly related to certain metallurgical phenomena, such as work hardening, recrystallization, precipitation and phase transformation.…”
