It was recalled that dislocation-loop formation in yttria fully-stabilized zirconia single crystals had been observed by means of transmission electron microscopy. Two different explanations had been proposed in order to account for loop formation. Original experiments were presented here which focussed upon a comparison of the 2 models. It was concluded that the cause of the loops was the precipitation of a second phase, as enhanced by heating in the electron beam.
