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.
