Superplastic ceramics have potential ability for applications to atomic energy fields. Up to date, however, as far as we know, there have been few studies concerning the effects of irradiation on the properties of the superplastic ceramics. In this study, the effect of Zr ion irradiation on some mechanical properties of a typical superplastic ceramic, 3mol% yttria stabilized tetragonal zirconia polycrystal(3Y-TZP)were examined and discussed. The 3Y-TZP specimens were irradiated by Zr^<11+> ions with 130MeV at fluence level of 2.1×10^<13> and 1.5×10^<14>ions/cm^2 in the TANDEM accelerator at Tokai Research Establishment of JAEA. Irradiated specimens were annealed at temperatures ranging from 573K to 1473K followed by furnace cooling and its mechanical properties were investigated after annealing. The influence of Zr ion irradiation on the mechanical properties almost disappeared when the irradiated 3Y-TZP was subsequently heated to 1473K
