Alumina–zirconia composites Al2O3–20 vol. % yttria stabilized zirconia containing twotypes of yttria stabilized zirconia: 3mol% yttria doped ZrO2 and 8mol% yttria doped ZrO2 wereconsolidated very rapidly to full density by high frequency induction heating sintering (HFIHS). Acomparison between 3YSZ and 8YSZ as a second phase toughening alumina has been made. Effectsof sintering temperature on the mechanical properties have been studied. The consolidated sampleswere investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). Themicrohardness, strength and toughness of the composites are determined. The results showed that,3YSZ is most effective as a second phase toughening alumina then 8YSZ. Al2O3-3YSZ compositeswith higher mechanical properties and small grain size were successfully developed at relatively lowtemperatures through this technique
