Abstract [en]

Austenitic heat resistant steel Sanicro 25 developed for high temperature applications in power generation industry has been subjected to selected low cycle fatigue tests at ambient and at elevated temperature. Saturated hysteresis loops at both temperatures were analyzed to deduce the probability density distribution of the internal critical stresses and to estimate the contribution of the effective stress for different strain amplitudes. The internal structure of the material at room and elevated temperature was studied using transmission electron microscopy and the results were discussed in relation to the cyclic stress- strain response
