The development of the crystallographic preferred orientation (texture) of polycrystalline pyrrhotite from Sullivan mine, Canada, and Cerro de Pasco, Peru was determined by neutron texture analyses before and after experimental deformation. The pyrrhotite ore from Sullivan has an initial texture with a distinct c-axis maximum perpendicular to the foliation whereas the ore from Cerro de Pasco shows a weak and moreover inhomogeneous texture within the specimen.The deformation texture and deformation behaviour of samples from Sullivan were investigated as a function of temperature, total strain and the angle between the compression axis and the initial caxis maximum. The deformation textures show the influence of different activated glide modes as a function of the compression direction and temperature. Investigations of the deformation texture and deformation behaviour of samples from Cerro de Pasco were carded out as a function of temperature, total strain and strain rate. The inhomogeneous texture of the starting material did not allow to draw conclusions about the texture development as a function of strain rate and temperature. Nevertheless the preferred orientation of the c-axes parallel to the compression axis becomes more evident with increasing total strain.

“…The same holds, however, equally well for all other classes of crystalline materials, such as ceramics, crystalline polymers and composites including geological or even biological materials (see e.g. Bunge, 1997). Texture measurement is therefore necessary in order to understand the properties of polycrystalline materials of any kind.…”

Texture measurement with short-wave X-ray synchrotron radiation in the range of ! 9 0.1 A Ê is described. The measurements were carried out with the multipurpose diffraction instrument at the high-®eld wiggler, high-energy beamline BW5 at HASYLAB. The instrument was equipped with an on-line image-plate area detector for diffraction-image registration and a Eulerian cradle for sample orientation. The particular features of texture measurement with the BW5 instrument are: good resolution in the Bragg angle, extremely high angular resolution in crystal orientation (pole-®gure angles) and particularly high penetration depth of several millimetres to centimetres, comparable with that of neutrons but at high spatial resolution. Several examples illustrate the particular advantages of this method for texture studies using large or encased samples (in situ studies in complicated environments, such as cryostats, furnaces, vacuum or pressure chambers, with no serious window problems). This allows, among others, non-destructive texture analysis in technological parts and whole components. Because of the extremely high beam intensity (short exposure times) compared with all other methods of texture measurement, the new technique is particularly suited for the study of large sample series (as is often necessary in industrial applications).

“…For the sake of completeness, Figure 21 is also continued to the long-range side beyond the classical X-ray texture analysis. There is, on the first place, neutron diffraction texture analysis [44] which is used particularly for two purposes (within the context of the present paper). These are, on the one hand, the measurement of global textures with the highest possible statistical relevance in order to average out inhomogeneities.…”

A microstructure function, G(x), is introduced as a general description of microstructure by considering simultaneously the spatial arrangement of phases, i(x), of crystallographic orientations, g(x), as well as of lattice defects and residual stress, D(x). Particular emphasis is laid on the orientation–location distribution function, g(x), which is the quantification of orientation stereology. From this function the classical texture as well as the classical (grain) stereology can be derived (but not vice versa). Recently new techniques of diffraction scanning electron microscopy have been developed for the acquisition of g(x) with the scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
