Texture after ECAP of a cube-oriented Ni single crystal
چکیده انگلیسی

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