A Growth Kinetics Study and Simulation for Recrystallized Ferrite Grains under the Annealing of Automotive Steel Cold-Rolled Sheets

The study results show the normal growth of recrystallized ferrite grains under the isothermal annealing of cold-rolled sheets made of five automotive steels (DX54D, HX260YD, CR210B2, 08ps, HX300LAD) obtained using a Gleeble 3800 experimental system. Based on the obtained data, a mathematical model...

Description
Summary:The study results show the normal growth of recrystallized ferrite grains under the isothermal annealing of cold-rolled sheets made of five automotive steels (DX54D, HX260YD, CR210B2, 08ps, HX300LAD) obtained using a Gleeble 3800 experimental system. Based on the obtained data, a mathematical model of this process has been developed. The simulation results obtained for the kinetics of ferrite grain growth in a practically important annealing temperature range agree well with the experimental data.
