Combined mechanism for the hardening of a ZrO2-Y2O3 ceramic
- 26 Downloads
The phase composition and mechanical properties have been examined for a ZrO2-Y2O3 ceramic having a combined hardening mechanism, which was made by high-temperature sintering under vacuum. The mechanism enables one to alter the properties of the zirconium dioxide base ceramic substantially. The material has a combination of high strength and toughness because of the high viscosity of the untransformed part of the material, which produces an additional strengthening effect along with the transformational hardening.
