Abstract


Fe-14Cr-0.2Ti-0.3Y2O3, ODS alloy samples are irradiated with 880 keV Fe+ ions at 230 K and 300 K upto a damage of 40 dpa at the surface. Transmission electron microscopy studies reveal a reduction in sizes of oxide dispersions in the ion irradiated alloys as compared to the as-prepared specimens; with greater diminution for samples irradiated at 230 K. Although the ion irradiation conditions (stage III) are favorable for vacancies to couple with solute atoms to cause precipitate growth, it is shown that such effects are less pronounced here and the ballistic effects dominate to cause oxide particle dissolution.
