Abstract

The evolution of radiation-induced damage in fully-stabilized, cubic zirconia and in pure, unstabilized, monoclinic zirconia, was investigated using Rutherford backscattering spectrometry and ion channeling, along with X-ray diffraction and transmission electron microscopy. FSZ crystals were irradiated with 340-400 KeV Xe++ ions and at temperatures ranging from 170 to 300K, or with 127I+ ions at temperature ranging from 300 to 1170K. No amorphization of zirconia was found under any irradiation condition, though in the case of 72 MeVI+ ion irradiation's, the irradiation-induced defect microstructure was observed to produce de-channeling effects in RBS/C measurements that reach the random level.
