Creep Behaviour of Advanced Power Plant Steels after Long-Term Isothermal Ageing Steels
Original language description
In this paper we tried to model the creep-strength degradation of selected advanced creep resistant steels which occurs under operating conditions. In order to accelerate some microstructure changes and thus to simulate degradation processes in long-termservice, isothermal ageing at 650°C for 10 000 h was applied to P91, P92 and P23 steels in their as-received states. The tensile creep tests were performed at temperature 600°C in argon atmosphere on all steels both in the as-received state and after isothermal ageing, in an effort to obtain a more complete description of the role of microstructure stability in high temperature creep of these steels. Creep tests were followed by microstructure investigations by means of transmission and scanning electron microscopy and by the thermodynamic calculations. The applicability of the creep tests was verified by the theoretical modelling of the phase equilibrium at different temperatures.
