Comparison of Numerical Simulation and Experiment for the Microstructure Development of a Cold-Rolled Multiphase Steel during Annealing

Article Preview

Abstract:

JAMK model, developed as part of RFSR-project “VADPsheets”, was applied to analyse different time temperature cycles from industrial time temperature cycle. The results of numerical simulation are compared with experimentally determined mechanical properties and microstructures. By distinguishing of recrystallized ferrite, ferrite after transformation, tempered martensite, bainite and martensite can be explained the experimentally obtained mechanical properties. The results of simulation can be used to optimizing the properties and to generate a better understanding of process parameters.
