Abstract
The effect of deformation type on structural changes in Al- and Ti-based amorphous alloys has been studied using the methods of X-ray diffraction, scanning and transmission electron microscopy. The high pressure torsion and multiple rolling methods were chosen for the deformation. It is shown that under deformation by high pressure torsion and multiple rolling methods a large number of shear bands are formed on the sample surface. Although the bands density is roughly equal, the fraction of the nanocrystalline phase forming during deformation in the case of high pressure torsion is greater than that under multiple rolling deformation. The number of shear bands and the fraction of the nanocrystalline phase decrease as the distance from the sample surface increases.
