The behavior of the dispersed droplets during elongation is in a good agreement with a prediction of the modified capillary number model. The phase structure changes after the elongation was studied in relaxation and recovery modes. Fro the morphology study using scanning electron microscopy and small-angle X-ray scattering the dimensions of the dispersed particles and their degree of orientation were estimated. It was shown that the SAXS as an integral method gives new additional information which is hardly accessible by SEM as a method providing local information about discrete locations in the sample. The results of both methods proved that the stress in the sample is a decisive parameter determining the morphology development after cessation of the flow.
