| Abstract: | High-temperature double-pass compression was conducted on Q 345E high strength low alloy （ HSLA） steel by using Gleeble-1500D thermal stimulator, in order to analyze the softening behaviour of deformed austenite of Q345E steel under different parameters and the influence of these parameters on the static softening process .By adop-ting 0.2%stress compensation method , the recrystallized percentage was defined , the static recrystallization activation energy of Q345E was also determined, the kinetics model of static recrystallization as well as the model of grain size e-volution were established . |
