Model ODS alloy containing Fe-0.3% yttria was prepared by ball milling and hipping at high temperature and the effect of irradiation on stability of yttria nanoclusters in model ODS alloy is studied by dual beam ion irradiation using 5 MeV Fe{sup +} and 1.5 MeV He{sup +} ions. TEM studies on irradiated sample show that these particles are stable at 25 dpa and 40 appm He concentration. However, at 80 dpa and 360 appm He concentration Yttria particles were found to be unstable as evidenced from increase in average particle size and particle size distribution.
