Texture studies of cold rolled steel, Cu and Ni by neutron diffraction

The submitted contribution deals with texture investigations of some polycrystalline materials subjected to cold rolling process. Using neutron diffraction the texture of rolled steel, Cu and electrolytic Ni having the cubic BCC or FCC lattices were studied. On the basis of pole figures for Fe(1 1 0), Fe(2 0 0), Fe(1 1 2), Cu(1 1 1), Cu(2 0 0), Cu(2 2 0) and Ni(1 1 1), Ni(2 0 0), Ni(2 20), orientation distribution function (ODF) fully describing the texture of individual samples, could be determined (Wenk and Kocks, Metall. Trans. A18 (1987) 1083, Kallend et al. Mater. Sci. Eng. A132 (1991)). It has been found that cold rolling significantly changes the texture and a complete anisotropy of the original material. Cold rolling as a specific method of metal forming creates in the rolled material a fibrous structure with alpha and gamma fibres. (C) 2000 Elsevier Science B.V. All rights reserved.
