The Raman spectra of ZYA system [ 60Wt % ZrO 2 ( 2.25mol % Y 2O 3 ) 40Wt % α Al 2O 3 ] were measured before and after it was pressed . The results proved the toughening mechanism of phase transformation from tetragonal ZrO 2 to monoclinic .
测试了60Wt%ZrO2（2.25mol%Y2O3）－40Wt%α－Al2O3（ZYA）粉末样品受机械压力前后的拉曼光谱，并由此证明了四方相ZrO2陶瓷基质的相变增韧机制。
