Abstract
The influence of temperature on elastic modulus and strength of 9 mol% MgO-containing partially stabilized zirconia (Mg-PSZ) aged around 110 0-degrees-C was studied. Elastic moduli on heating increased with incr easing temperature after showing minimum values around 600-degrees-C. Elastic moduli on cooling monotonously increased with decreasing tempe rature. The strength of as-recieved specimen A have a maximum value ar ound 200-degrees-C. The strengths of aged specimens on heating increas ed with increasing temperature after showing a minimum value around 60 0-degrees-C. On cooling, the strength of specimen B aged for 2 h incre ased remarkably with decreasing temperature to a maximum value at 450- degrees-C, and then decreased remarkably. On the other hand, the stren gth of specimen C aged for 8 h showed a constant value between 1000 an d 400-degrees-C and decreased slightly below 400-degrees-C.
