Abstract
Rolling textures in nanoscale multilayered thin films are found to differ markedly from textures observed in bulk
materials. Multilayered thin films consisting of alternating Cu and Nb layers with columnar grains were produced by
magnetron sputtering, with individual layer thickness ranging from 4 µm to 75 nm and Cu/Nb interfaces locally
satisfying the Kurdjumov­Sachs (K­S) orientation relations. After rolling to 80% effective strain, samples with a larger
initial layer thickness develop a bulk rolling texture while those with a smaller initial layer thickness display co-rotation
of Cu and Nb columnar grains about the interface normal, in order to preserve the K­S orientation relations. The
resulting K­S texture has 0 0 1 Nb parallel to and 1 1 0 Cu approximately 5° from the rolling direction. A crystal
