The defocusing effect in the reflexion technique for the determination of the preferred orientation using energy-dispersive x-ray diffraction (EDXRD) method is studied experimentally. The measurements show that the defocusing effect is dependent on the Bragg angle, the receiving slit width, the reflexion hkl and the metallurgical condition of the specimen. The defocusing correction or at least the optimizing of the measuring geometry is found to be necessary in quantitative texture measurements.
