Deformation mechanisms in yttria-stabilized cubic zirconia single crystals

This work attempts to give a unified picture of the microscopic mechanisms which control the plastic deformation in yttria-stabilized cubic zirconia single crystals, particularly for the soft orientation (uniaxial compression along the [1̄* * *2] crystallographic axis) at low, intermediate and high...
