Abstract

Single crystalline and ceramic solid solutions of (1−0.x)(ZrO2)−(0.x)(YO1.5) with x = 14−17 were implanted with high doses of Fe. Specific profile shapes were realised. The microstructure of the material before and after annealing was studied by conversion electron Mössbauer spectroscopy (CEMS), ion channeling and transmission electron microscopy (TEM). Initially Fe is present as metallic particles Fe0 and as Fe2+ and Fe3+ ions. Their relative abundancy depends on the implantation conditions. Annealing leads to complete oxidation (Fe3+) at low temperature and to the formation of microprecipitates of Fe2O3 (< 5 nm). A maximum of 4.5 × 1021 Fe cm−3 can be substitutionally incorporated for Zr. This Fe is present in a metastable state. Ion channeling and electron diffraction experiments revealed that high fluence Fe implantation does not result in amorphisation but in recrystallisation of the matrix.
