Abstract

Hot deformation is a crucial step in steel production, with vast markets served by material in the hot-rolled condition to specific microstructures and properties. Consequently, the improved understanding and quantification of this process have been and continue to be the subject of major modelling efforts worldwide. This project primarily addresses the phase transformations encountered and the resultant finished properties, in CMn and HSLA steels, encompassing experimental examination of mechanisms, material characterization (metallography, dilatometry, thermal analysis, hot and ambient properties) and computer model development. Much has been learnt form the direct comparison of experimental results from different partner sites and of alternative computer models. Additional aspects concerned IF and acicular ferrite steels, hot-rolled texture and finished properties of CMnTi strip, and investigation of local friction conditions at the roll-metal interface during hot rolling.

A novel and flexible computer programme has been developed to predict the phase transformation kinetics, proportions and characteristic sizes of austenite decomposition products under standard or accelerated cooling conditions. Its use can be either as a freestanding tool or as a subroutine connected to a metallurgical model of the hot-rolling process..
