Abstract
The influence of temperature on elastic modulus and strength of 9mol% MgO-containing partially stabilized zirconia (Mg-PSZ) aged around 1100°C was studied. Elastic moduli on heating increased with increasing temperature after showing minimum values around 600°C. Elastic moduli on cooling monotonously increased with decreasing temperature. The strength of as-recieved specimen A have a maximum value around 200°C. The strengths of aged specimens on heating increased with increasing temperature after showing a minimum value around 600°C. On cooling, the strength of specimen B aged for 2h increased remarkably with decreasing temperature to a maximum value at 450°C, and then decreased remarkably. On the other hand, the strength of specimen C aged for 8h showed a constant value between 1000 and 400°C and decreased slightly below 400°C.
