On the Recrystallization Characteristics and Kinetics of Two High-Si DQ&P steels

Microstructure evolution and static recrystallization kinetics in hot-deformed austenite of coarse-grained Mo-free and Mo containing low-carbon CrNiMnB ultrahigh-strength steels

“…12. These values fall in the range of Q app (177-283 kJ/mol) reported in literature for other steels [39]. The activation energy of SRX (Q rex ) depend on Q app , the power of strain rate q and the deformation activation energy (Q def ).…”

“…model that could predict the static recrystallization of various carbon and microalloyed steels [47]. All the reported values of q in literature fall within a small range − 0.11 to − 0.23 which indicates the weak dependency of SRX on the strain rate, irrespective of chemical composition [39]. Combining the above values for Q app , p, and q in Eq.…”

“…Combining the above values for Q app , p, and q in Eq. ( 1) with the power of grain size described by the relation s = 2.13d − 0.105 [39], the constant A for the two steels is obtained. Therefore, the SRX rate can be described using the following SRX equations:…”
