Effect of MgAl2O4 Particles on Characterization of Y2O3– ZrO2 System
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 percen...

| description | 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. |
