The nanocomposite CeO 2 /Y 2 O 3 partially stabilized zirconia (Ce‐ PSZ /Y‐ PSZ )‐toughened alumina was prepared by wet chemical simultaneous coprecipitation process. The thermal stability of phases and morphology of powders were characterized by TG ‐ DTA , FTIR , and FESEM . The microstructure, stabilization of phases and compositional analysis with different mol% CeO 2 /Y 2 O 3 ‐doped zirconia in alumina are characterized by FESEM , XRD , and EDAX spectra. Significant improvement in fracture toughness and flexural strength has been observed in 10 vol% of partially stabilized zirconia (2.5 mol% Y 2 O 3 in ZrO 2 /9 mol% CeO 2 in ZrO 2 )‐toughened alumina, which is suitable for high‐speed machining applications.
