主　　题：Gleeble-3500 low-alloy steel static recrystallization activation energy kinetics model 

摘      要：The static recrystallization behavior of low-alloy steel Q345B during double-pass hot compression deformation tests was investigated in the temperature range of 900-1000 ℃,the true strain range of 0.15-0.25 and the interpass time range of 0.5-50 s on Gleeble-3500 thermo-simulation *** results show that static recrystallization during the interpass time is *** the deformation temperature and strain increase,softening caused by static recrystallization is *** to the analysis and calculation of thermo-simulation data,the static recrystallization activation energy was obtained and static recrystallization kinetics model was ***,the error analysis of static recrystallization kinetics model proved that the model had good ***,this model provides a theoretical basis for static recrystallization（SRX）and will contribute to the development of multipass hot rolling process,in order to control the rolling process more accurately.
