摘要：

Plastic deformation in Y2O3-stabilized ZrO2 single crystals, oriented for single glide on the {001}〈110〉 system, has been studied at 1400°C. Stress-strain curves exhibit a yield drop which is due to dislocation multiplication but involves activation of secondary {111}〈11¯0〉 slip systems. X-ray topography revealed that dislocation walls perpendicular to the active slip planes formed at small strains and persisted throughout the deformation.
