摘要: The texture of a cube-oriented Ni single crystal after one-pass equal channel angular pressing (ECAP) was measured globally and locally by neutron synchrotron radiation, respectively. is characterized TD rotated cube, split C component partial B fiber. These components are heterogeneously distributed in the ECAP billet. Due to friction at die walls, cube mainly observed top bottom parts billet, dominates central part. experimental results with respect intensity, position from ideal orientation asymmetry splitting compared simulations taking into account grain fragmentation. Conclusions concerning polycrystal deformation drawn.
