INTERMETALLIC TEXTURE ANALYSIS BY X-RAY, NEUTRON AND ELECTRON BACKSCATTERED DIFFRACTION

Texture characterization of intermetallic materials implies to solve t he problem of overlapped pole figures of one or several phases when th ey are carried out by X-ray or neutron diffraction. Moreover, if the h armonic method is used to calculate the texture function, a complement ary iterative method must be introduced to define the total texture fu nction. A second iterative method must still be used to solve the prob lem of incomplete pole figures measured by X-ray diffraction in reflec tion. An other approach consists in using individual orientation measu rements, which allow to estimate the local texture which can be correl ated to the microstructure but also to the global one if the orientati on number is sufficient.
