Orientation Measured from Inverse Pole Figures

ORIENTATION MEASURED FROM INVERSE POLE FIGURES 

In another set of experiments, tensile specimens initially 0.015 in. thick were elongated to various extents, released, and subsequently X-rayed. The resulting data can be analyzed by pole figure techniques to give the complete orientation distribution of unit cells in the specimen. For the case of axial specimen 

Directions indicated are poles of crystallographic planes contours show the density with which these crystal directions are aligned parallel to the tensile axis in multiples of the density for a sample with no preferred orientation

Sheet textures may also be represented by inverse pole figures. Here three separate projections are needed to show the distribution of the sheet normal, rolling direction, and transverse direction. Figure 9-24(b) is such a projection for the normal direction of the steel sheet whose (110) pole figure was given in Fig. 9-20 it was calculated from the crystal orientation distribution mentioned in Sec. 9-8. The distribution of the normal direction is also shown in (c), for the same material. This distribution was measured directly in the following way. A powder pattern is made of the sheet in a diffractometer by the usual method, with the sheet equally...
