• Neutron diffraction topography was applied to the direct observation of the texture in Bridgman-grown Cu-5%Ge crystals with growth direction nearly parallel to [110]. The texture is composed of a layer-substructure constituting a hierarchy in the crystal texture : layers parallel to (001) ((001)-layer) are arrayed with the spacing of about 1 mm, and extend throughout the crystal nearly parallel to the growth direction. The (001)-layer is attached on its both sides with plates parallel to (100)- and (010)-planes. These layer-substructures correspond to the arrayed striations visible on the crystal surfaces. The substructure is different from both of the cellular- and the lineage-substructures hitherto proposed to describe the texture of Bridgman-grown crystals.
