MODELING THE DEVELOPMENT OF MICROSTRUCTURE DURING HOT-ROLLING AND COOLING

Empirically-based models are widely used throughout the industry to de scribe the evolution of microstructure during the thermomechanical tre atment of steel. There are growing demands for greater accuracy of pre diction over a wider range of steel composition and operating conditio ns. Both industry and universities worldwide are developing new models to meet these demands. This paper reviews some of the key issues and concludes that it is the development of physically-based models, tuned with actual process data, that has the potential to satisfy this need .
