Abstract Scope |
TRIP steels obtain their excellent formability due to the transformation of retained austenite to martensite during plastic deformation. The microalloying addition through Nb enhances ductility by delaying the onset of carbide precipitation to Al/ Si base TRIP steels. In this work, an ICME framework is used to integrate caster, reheating and hot-rolling operations to capture the dynamics of microstructure and mechanical properties evolution. The focus is on the deformation and precipitation kinetics during hot rolling of Nb micro-alloyed TRIP steel. The models include a transient heat transfer and a thermomechanical model to capture temperature evolution across the slab during casting, reheating and hot rolling operation. A multi-component equilibrium precipitate model is utilized to compute the precipitation kinetics of NbC and their influence on the evolving microstructure. The models are developed using OpenFOAM and Code-Aster and the effect of various process parameters on the precipitation kinetics and evolving microstructure are presented. |
