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.
