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.
