Single-phase polycrystalline metals undergoing severe plastic deformation develop steady-state textures that are characteristic of the mode of deformation. By contrast, we show via molecular statics simulations that Cu-Nb nano-composites reach a variety of different steady-state textures under a single mode of deformation. The final, steady state texture is shown to depend on the initial texture of the composite. This finding demonstrates that the range of bulk Cu-Nb nano-composite textures that may be made by severe plastic deformation is larger than previously demonstrated, with multiple plastically driven steady states accessible, depending on initial layer texture. We propose a modification of accumulative roll bonding with highly textured seed layers as a means of accessing different driven steady states.
