Abstract
Materials based on tetragonal zirconia polycrystals fully stabilized w ith CeO2 have been prepared starting from commercial powders. The mech anical properties of samples with different compositions were measured at room temperature and after quench tests. The effects of thermal tr eatments on the microstructure and crystal phases and their detrimenta l influence on strength, toughness and hardness were evaluated. Experi ments demonstrated that residual porosity and higher amounts of ceria favourably influence the retention of material properties after therma l treatment.
