| Outline of Final Research Achievements |
To provide a guidance for a reasonable material design to help developing new nuclear material, Fe-Cr-Ni ternary model alloy, each of which are main components of austenitic stainless steel, and high Ni alloy were investigated by means of in-situ observation during electron irradiation and microstructural observation for neutron-irradiated samples.
Concentration and flux of point defect were quantitatively evaluated and then effective factors (minor additives and precipitate etc) of material engineering for suppressing radiation-induced segregation and retarding onset of void swelling were successfully extracted.
