| Abstract Scope |
An accurate thermo-microstructural modeling setup was developed to model the kinetic of static recrystallization during annealing of hydroformed steel tube under non-isothermal condition. In this model, a coupled Cellular Automata and Finite Element thermal model was implemented to predict the kinetic of static recrystallization, which also accounts for the impact of multiaxial deformation and annealing temperature regime. First, an exact analytical solution was developed to calculate the flow behavior of steel tube during hydroforming experiment based on the data extracted from digital image correlation measurements. Second, the actual microstructure and orientation of the as-deformed material was obtained with EBSD test. Third, the calculated deformation characteristics as well as the obtained crystallographic and microstructural data were imported to the developed Finite Element-Cellular Automata model to predict the progress of static recrystallization and temperature changes during annealing. The results show that there is a reasonable agreement between the experimental data and predictions, confirming the accuracy of developed modeling setup in prediction of the progress of static recrystallization within hydroformed steel tubes. |
