Mechanical properties of biocompatible Y-TZP/Al2O3 composites obtained from mechanically alloyed powders

In this study, an alumina-toughened zirconia composite (ATZ) was developed from mechanical alloyed nano-scale powder mixtures using low-sintering temperatures. A powder mixture, composed of 80 wt.% Y-TZP, ZrO 2 (3 mol.% Y 2 O 3 ), and 20 wt.% Al 2 O 3 , was prepared by mechanical alloying (MA) in a...
