Fully stabilized cubic ZrO 2 single crystals containing various Y 2 O 3 concentrations were deformed at 1400°C in air. The orientation chosen favored (001)(110) slip, which was confirmed by slip‐trace analysis and transmission electron microscopy; (111)(110) slip could also be activated. The yield and flow stresses increased with increasing Y 2 O 3 concentration, and stress‐strain curves were dominated by a region of zero work hardening from very small strains for all compositions.
