Intermetallic Texture Analysis by X-Ray, Neutron and Electron Backscattered Diffraction

Abstract. Texture characterization of intermetallic materials implies to solve the problem of overlapped pole figures of one or several phases when they are carried out by X-ray or neutron diffraction. Moreover, if the harmonic method is used to calculate the texture function, a complementary iterative method must be introduced to define the total texture function. A second iterative method must still be used to solve the problem of incomplete pole tigures measured by X-ray diffraction in reflection. An other approach consists in using individual orientation measurements, which allow to estimate the local texture which can be correlated to the microstructure but also to the global one if the orientation number is sufficient. 1
