SUMMARY
sro
Thermal cycling of rolled duplex steels in the temperature range between room temperature and fatig
1050;{C causes plastic deformations of the material. These deformations are influenced by the mi-
crostructural changes of the duplex structure. By characterising its variable phase geometry existing rn
modelling approaches can be optimised and saturation effects developing after thermally-induced (Oh
cyclic deformation can be described.
