摘要
Constant strain rate tests have been performed on cubic ZrO2 single crystals stabilized with 9.4 mol% Y2O3 in an argon atmosphere at temperatures up to 1750-degrees-C. Crystals were oriented along the [112] direction for easy {001}[110] slip. Mechanical data have been correlated with transmission electron microscopy observations in order to characterize the strain rate-controlling mechanism. At temperatures above 1500-degrees-C, a recovery mechanism by dislocation climb has been obtained with an activation energy of about 510 kJ/mol, corresponding to the cation diffusion.
