Microstructural characterization of second phases in X10CrMoVNb9-1 and 12CrMoWCuVNb steels after long steam exposure time at 550 oC
Original language description
Microstructural changes in high alloy (9 - 12 %Cr) creep resistant martensitic X10CrMoVNb9-1 and 12CrMoWCuVNb steels after 100 000 h of steam exposure at 550 oC have been studied using scanning transmission electron microscopy. Precipitates were identified using electron diffraction patterns and energy dispersive X-ray spectroscopy analysis. After long time exposure, a significant coarsening of M23C6 carbides, and intensive precipitation of the coarse Laves phase were observed. Moreover, in the 12CrMoWCuVNb steel, a low amount of the modified Z-phase particles was detected. The microstructures of the X10CrMoVNb9-1 and 12CrMoWCuVNb steels after 100 000 h of exposure differ in several aspects.
