Defocusing correction for the measurement of preferred orientation
Tóm tắt
A method utilizing textural symmetry is described for establishing the defocusing correction in the Schulz reflection technique of pole figure analysis. An offset specimen is necessary for this determination and sample material identical to that under study is used. This avoids certain difficulties associated with the conventional textureless specimen procedure. The new method is compared with the earlier method in studies of copper, and changes in the defocusing function with receiver slit width and Bragg angle are evaluated. Factors affecting the choice of specimen orientation are examined for the case of orthotropic symmetry.
