Abstract

Al₂O₃-ZrO₂ (AZ) eutectic fibres containing 41.05 wt% ZrO₂ and 2.03 wt% Y₂O₃ were produced via inviscid melt spinning (IMS). Scanning electron microscopy (SEM) was used to examine the morphology of the as-spun AZ fibre. Differential thermal analysis (DTA) and X-ray diffraction (XRD) were used to investigate the phase transformations in this fibre. The XRD pattern of the as-spun AZ fibre showed tetragonal ZrO₂, α-Al₂O₃, and non-equilibrium δ-Al₂O₃ phase formation. The DTA curve of the as-spun AZ fibre showed only one endothermic peak representing the phase transformation of δ-Al₂O₃ to α-Al₂O₃. This phase transformation was confirmed by analysing the XRD pattern of heat-treated AZ fibre.
