| Abstract Scope |
Yttria-stabilized zirconia (YSZ) is one of the most commonly used structural ceramics due to its excellent mechanical properties such as high fracture toughness and flexural strength. These distinguished properties are attributed to the phase transformation toughening, which refers to the phenomenon that tetragonal phase experiences a phase transition to the stable and large monoclinic phase around a propagating crack. Adding dispersed particles, like oxides or non-oxides, to zirconia would additionally be enhancing mechanical properties of zirconia.
In this study, YSZ materials with WC dispersion are fabricated by hot pressing as well as vacuum sintering. With different amount of WC addition, the mechanical properties are examined. The relation between microstructures and those properties is discussed as well. |
