| Abstract | ||
| In this study, four samples composite materials used for manufacturing by using uniaxially technique compressed into cylindrical pellets. The matrix materials of these composites are: yttrium oxide + zirconia (3mol%Y2O3+ZrO2), reinforced with spinel (MgAl2O4) particles which is added in three percentages (5, 10, 15 % wt) to the matrix. Additionally there are pellet without reinforced and with spinel (MgAl2O4) particles, then sintering at temperatures 1550 ºC for 2 h. The density and the apparent porosity of the sintered pellet were measured by the Archimedes drainage method, the microstructure features and the phase identification were examined using SEM and XRD; and the mechanical properties such as hardness and toughness were determined using Vickers indentations. | ||
