Influence of strain rate on deformation behaviour, austenite structure & kinetik of Gamma/Alpha transformation

Ziel

This project aims to investigate the influence of the strain rate on the behaviour of steels in the course of hot rolling performed mainly in the lower austenite range for hot strip and wire rod mills. Flow curves will be recorded in single and multiple pass deformations. The changes in the flow stresses, the resulting changes in the grain structure, the strain hardening, the precipitation behaviour, softening during deformation and interpass times, the deformation heat and the kinetics of the transformation will be measured and analysed. On the basis of the collected experimental data, the influence of the strain rate on the characteristic material processes which are relevant to the simulation of hot rolling will be described by mathematical equations. For this purpose existing models will be utilised and, if necessary, new models created.
