Effect of precipitates on long-term creep deformation properties of P92 and P122 type advanced ferritic steels for USC power plants

Long-term creep rupture strengths and the microstructural stability of ASME P92 and P122 pipes have been studied using creep testing at the temperatures from 550 to 700 °C and detailed scanning transmission electron microscopy. Creep rupture strength of P92 is found to be more stable than that of P1...
