The work is devoted to the study of the formation of large blocks from aluminum alloy AA5056 by electron-beam additive technology with subsequent friction stir processing of the material. Conducted studies of the sample structure show that during the processing of additively produced samples there is a refinement of the material grain structure in the stir zone with the removal of defects such as pores and small discontinuities. Large defects of the additively produced material can be eliminated by the friction stir processing only partially, with the formation of defects such as the Lazy “S” or the joint line one in the stir zone.
