Structure and Mechanical Properties of ZrO2 Toughened Al2O3 Ceramic

    Graphical Abstract
    • Abstract
  • Y2O3 stabilized ZrO2 toughened nanometer Al2O3,μmAl2O3 ceramic composites are obtained with a high-shear two-roll mill process.Their structure and mechanical properties are studied respectively.Further more,the microstructure of these ceramic composites was designed through mixing three grain-size powders.A fine ceramic composites of ZrO2/nmAl2O3/μmAl2O3 is obtained.This ceramic composites can be densified above 98% of theoretical at 1550℃.Its flexual strengh and toughness are fine.
