Abstract

Twin-roll cast Al-Mg-Sc alloy was processed by equal-channel angular pressing in order to produce ultrafine-grained structure. The microstructure was studied by the means of scanning electron microscopy, electron back-scatter diffraction and transmission electron microscopy. During in-situ heating partial recrystallization occurred in the bulk of the material. Near the edge of the sample observed in transmission electron microscope the deformed microstructure was retained, as in the 2D foil processes of recrystallization proceed slower and at higher temperatures compared to the 3D materials.
