Texture Analyses by Synchrotron X-rays and Neutrons

Abstract

In the last decades, there have been significant advances in texture measurement techniques and analyzing software. This chapter introduces various texture measuring techniques, from laboratory machines to large facilities. By comparing the characteristics of each method, a guideline to a more effective use for different research purposes is provided. Neutron diffraction is favored for a large sample volume and coarse-grained materials, for averaging over texture gradients for a direct correlation to macroscopic materials behavior as well as for multi-phase gradient materials. Synchrotron diffraction is favored for global textures on a small volume scale and for fast in situ experiments. The high penetration power of neutrons and high-energy X-rays into solid matter and a high freedom to install various devices, e.g. furnace or loading devices, directly inthe beam allow a wide range of possibilities of in situ texture analysis under different sample conditions. Moreover, important features of texture measurements at large facilities are demonstrated by giving selected examples.
