摘要
The yield stress of cubic stabilized zirconia single crystals with yttria concentrations between 24 to 32 mol % has been studied for temperatures of 1400 degreesC by compression experiments on the [112] crystalographic axis at constant compressive strain rate. The yield stress reaches a value of 300 MPa, remaining constant for the higher concentration studied, and being also independent of the annealing time in air. The plastic behavior is discussed in terms of the interaction of dislocations with the free yttrium defects.
