Modifcation of microstructure parameters of severely deformed 1050 aluminum after 5 years of recovery at ambient temperature was studied. The samples of 1050 aluminum were extruded using ECAP technique. The EBSD maps were recordedfor the initial material and for the deformed samples. Next, the latter samples were left at ambient temperature during 5 yearsand a full EBSD study of the material was repeated. It was found that all microstructure parameters and textures have changedafter this period. This is due to recovery and partial recrystallization, which took place in the samples during 5 years. Thepresented modifcations of material microstructure are important, e.g., in the aspect of long time service of mechanical partsproduced by severe plastic deformation techniques
