Abstract

The paper presents the results of research on fatigue life of GX12CrMoVNbN9 – 1 (GP91) cast steel in the as-received state and after ageing at the temperature of 600 °C. The fatigue of low cycle scope was performed at the temperature of 600 oC at the strain amplitude level of εac= 0.25 ÷ 0.60%. Analysis of the tests carried out has shown that the examined cast steel is characterized by strong cyclic softening without an evident period of stabilization. Ageing of GP91 cast steel leads to the fatigue life reduction by ca. 7 to ca. 35%, depending on the level of strain amplitude εacin comparison with the as-received condition.
