چکیده انگلیسی
The microstructure of Cr16 ferritic steel reinforced with yttrium oxide particles and KP4 ODS alloy irradiated with 167 MeV xenon and 700 MeV bismuth ions at 300 K has been studied using high resolution transmission electron microscopy. Amorphous latent tracks were identified in (Cr, W)23C6, Y2Ti2O7 and Y2TiO5 nanoparticles in Cr16 at a Bi ion fluence of 1.5 Ã 1012 cmâ2. It was found that multiple track overlapping leads to complete amorphization of carbide and (Y, Ti) oxide particles in Cr16 specimens. No latent tracks have been observed in Y4Al2O9 particles in KP4 irradiated with Bi ions. Small oxide particles (â¼5 nm), in KP4 alloy, remain crystalline at Bi ion fluences up to 1.5 Ã 1013 cmâ2, while subsurface regions in large (â¼20 nm) particles were amorphized. Xe ion irradiation at fluences of 1 Ã 1014 cmâ2 and 1.5 Ã 1015 cmâ2 resulted in amorphization of small Y4Al2O9 oxide particles while the amorphous bodies of large particles were found to contain small crystalline inclusions.
