Paper Abstract

In recent years, microstructure engineering has gamed significant attention, with the goal being to develop predictive tools which quantitatively link the operational parameters of an industrial process to the properties of the product it makes. Recent emphasis has been on developing microstructure models for hot strip rolling of advanced low and ultra low carbon steels [1 -3]. To improve mechanical properties of these steels, cooling paths have to be designed which optimize the ferrite microstructure resulting from the austenite decomposition. Accelerated cooling on the mn-out table of a hot strip mill has become an accepted tool to refme ferrite grain size by lowering the austenite-to-ferrite transfonnation temperature. Although phase transformations in steels have been investigated more extensively than those in any other material, there is still a considerable need to gain insight into the nucleation and growth mechanisms of ferrite under industrial cooling conditions. The present paper summarizes approaches to model the transformation kinetics utilizing nucleation and growth theories for ferrite.
