Austenite Recrystallization Model of High Ti Microalloyed Steels

Xue Gang Xiong

Abstract

Through the thermal simulation test, the curves of austenite recrystallization kinetics is recorded, the influence of the parameters including deformation temperature, strain and strain rate on the austenite recrystallization fraction of Ti microalloyed steels is studied, the recrystallization kinetics equation is calculated, and the austenite recrystallization model of the test steel is obtained. The results improve that Ti inhibits both the dynamic and static austenite recrystallization in high Ti microalloyed steels.
