The X22CrMoV121 steel has been investigated with regard to their stress-strain response in low cycle fatigue test at the temperature range 413K – 773K. The cyclic deformation behaviour is characterised by a pronounced cyclic hardening all over the range. Increasing temperatures lead to an increase in cyclic work hardening degree. The corresponding microstructure is analysed by optical and transmission electron microscopy. For comparison the different mechanical behaviour of the quenched and tempered material under similar test conditions were also examined.
