| Abstract: | Dislocation loop formation in yttria fully stabilized zirconia single crystals observed in a transmission electron microscope has been reported in the literature. To account for the loop formation, two different explanations have been proposed. Here we present original experiments focusing on a comparison of the two models. We conclude that the origin of the loops is precipitation of a second phase, enhanced by heating in the electron beam. |
