Description
| - Superplastically deformed samples of 3 mol% yttria stabilized tetragonal zirconia polycrystals (3Y-TZP) and 3Y-TZP with 20wt% of Al2O3 were studied by SANS with the aim to compare cavitation behaviours under different deformation conditions. Though the average size of cavities formed during deformation is so large that they can be measured only by high-resolution SANS techniques, conventional SANS method permitted us to measure their specific surface and aspect ratio quite effectively. Analysis of the 2-dimentional SANS data clearly showed two qualitatively different cavitation regimes corresponding to the low stress (low strain-rate and high temperature) and high stress conditions, respectively. In the latter case, a new type of flat pores transversal to the tension axis was observed, in addition to the usually present slightly prolate cavities.
