Static recrystallization behavior of high strength steel with high Ti microalloying was studied by a Gleeble 3500 thermal simulation testing machine and stress relaxation method.The results show that the static recrystallization process is accelerated and the deformation rate has little effect on the static recrystallization under high deformation temperature and large deformation.The calculated activation energy of static recrystallization is Qrex=276.45 kJ/mol,which confirms that the microalloy element Ti can inhibit recrystallization.Based on Avarami equation,the static recrystallization model of experimental steel has been established.
