ABSTRACT
A microtexture is, essentially, a population of individual orientations that can be linked to their location in a specimen and are obtained usually by an electron diffraction technique as described in Chapters 7 and 8. These two factors-the discrete nature of the orientation data and their direct link to the microstructure-introduce a much broader and more complex scenario for data evaluation and representation than that for macrotextures, since in the latter case the orientation data evaluation usually involves only direct representation in the form of pole gures and subsequently calculation of an ODF (Chapter 5). The large variety of situations that can be addressed by means of individual orientation measurements and orientation mapping requires many more formats for the representation and interpretation of the measurements.
