Abstract—The results of an investigation into the influence of the degree of deformation on the structure of
components of the layered steel–aluminum composite are presented. It is shown that the noticeable structural
variations start from reduction ratio > 75%, or e > 1.54 in logarithmic units. The plastic deformation mecha-
nism of a brittle intermetallic layer is described. It is shown that the viscoplastic intermediate layer of the steel–
aluminum layered composite can be obtained by rolling when bringing the deformation ratio to 90%. As for the
submicron structure, it can be obtained at > 95%, or e > 3.

Keywords: layered composite, intermetallic compound, intense plastic deformation, rolling, deformation ratio,
nanostructure, structural fragmentation
