Abstract

Microstructure of Cr16 ferritic steel reinforced with yttrium oxide particles and KP4 oxide dispersion strengthened (ODS) alloy irradiated with 167 MeV xenon and 700 MeV bismuth ions at 300 K has been studied using high resolution transmission electron microscopy. It was found that Bi ion irradiation at fluences more than 1013 cm-2 leads to complete amorphization of oxide particles in Cr16 samples, while central regions of large (∼20 nm) particles and small oxides (∼5 nm) in KP4 steel remain crystalline. The Xe ion irradiation effect consists in polycrystallization of single crystalline oxide particles. Small oxide particles at 1.5×1015 Xe×cm-2 are fragmented to quasi-amorphous state. No dissolution of nanoparticles has been revealed in all studied samples.
