Abstract
The phase structure and structural evolution of the binary Al-Fe alloys received from mixture of elemental powders by intensive plastic deformation under pressure is studied. It is revealed that solubility of iron in aluminum at a room tem-perature increases to 1 ат. %. It is established that the size of grains depends on the metal contents in the initial mixture and the degree of plastic deformation. Regions with amor-phous sites are observed in alloys at the iron content > 10 at.%. It is shown that the shape of a surface of fracture finds a certain causal relation with the iron content in the synthe-sized alloy.
