Recrystallization Modelling of Hot Deformed Si-Mn TRIP Steel

By means of hot compression single and double hit experiments, the kinetics of dynamic and static recrys-tallization in hot-rolled Si-Mn TRIP steel was studied, and the emphasis was put on the influence of high silicon content. The results show that the calculated parameters are consistent with the experimental ones, and addition of silicon retards both dynamic and static recrystallization as well as increases the flow stress of austenite, and the non-recrystallization zone can be enlarged by increasing the silicon contents.
