Accumulative rolling bonding (ARB) is a typical severe plastic deformation process that has two exciting capabilities: (a) metals can be processed to high strains without any change in dimension, and (b) multilayered composite are achievable via combination of different metals. In this study, Fe/Ni multilayered composite is fabricated using ARB, and its recrystallization behaviour at elevated temperature is investigated employing Electron Backscatter Diffraction (EBSD). Texture-based Schmidt factor calculation of the combined layers reveals an overall balance in texture components, which points to a reduction in planar anisotropy.  The ability to fabricate multilayered composite by ARB provides an opportunity for controlling the planar anisotropy and improving the drawability of metal sheets.
