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.
