摘要: Abstract Ferritic–martensitic (F/M) alloys are expected to play an important role as cladding or structural components in Generation IV and other advanced nuclear systems operating the temperature range 350–700 °C doses up 200 displacements per atom (dpa). Oxide dispersion strengthened (ODS) F/M steels have been developed operate at higher temperatures than traditional steels. These contain nanometer-sized Y–Ti–O nanoclusters for additional strengthening. A proton irradiation 1 dpa 525 °C has performed on a 9Cr ODS steel determine nanocluster stability low dose. The evolution of population composition nanocluster–matrix interface were studied using electron microscopy probe tomography. data from this study contrasted those previous heavy-ion irradiated steel.
