Abstract

There is a need to increase the operation temperature of 9Cr ferritic/martensitic steels to improve the efficiency of future power plants. The key is to improve the thermal stability of the microstructure above 600-650 °C. With this aim in mind, this investigation has focused on exploring two different strategies to increase this operation temperature; both mainly aimed at (but not only) refining the size of MX precipitates and increasing its number density and thermal stability.
