Abstract  Nano-structured oxide dispersion strengthened (ODS) ferritic steels are the leading candidates of fuel cladding for future fast neutron feeder reactors due to their excellent radiation tolerance and high-temperature creep strength. A 14Cr-ODS steel was prepared by mechanical alloy (MA) and hot isostatic pressing (HIP) methods. The morphology and microstructure of MA powders and the microstructure of 14Cr-ODS steel were characterized by SEM, XRD, EDS and TEM. The results showed that during the MA, the size of powders increases with the increasing milling time (0-2 h), then decreases with the increasing milling time (2-70 h). The grain size decreases with the increasing milling time. The alloying elements and Y2O3 dissolve fully into Fe matrix during MA after 70 h. Three kinds of precipitates are observed in the consolidated 14Cr-ODS steel: very high number density of nanoscale Y-Ti-O-rich clusters, few pyrochlore structure Y2Ti2O7 particles and some Cr-Ti-rich particles. The clusters exhibits good high temperature stability at\linebreak 1250 ℃ for 8 h, while the density of Y2Ti2O7 precipitates increases.
Key words:  ODS steel      mechanical alloying      hot isostatic pressing      Y-Ti-O-rich cluster      stability
