Abstract Scope This talk will present our efforts to characterize the processing and microstructure of FCC/BCC metallic nanolaminates manufactured via accumulative roll bonding. Efforts behind achieving nanoscale layers in the Cu/Nb, Cu/Fe, and Ag/Fe systems will be presented in the form of material microstructure, texture, and detailed deformation processing history. This history will include in situ data from the rolling process such as material temperature, roll gap and deflection, roll load across the width of the rolls, and roll speed. This data is used to understand microstructural changes which could lead to material failure during the roll bonding process. The effect of intermittent heat treatments on the success of processing is also investigated. Texture as a function of strain and layer thickness will be explored and compared at the micron and nanoscales for these materials.
