Abstract

A software has been developed to determine optimal rolling passes in thermo-mechanical (TM) rolling in order to obtain a fine microstructure. It includes models of the effect of strain, precipitates, static and dynamic recrystallization and austenite grain size on the final grain size. It was also used to study the effect of different long interpass times during thermo-mechanical rolling of heavy plates. The predicted grain sizes for four different cases were compared with experimental results.
