Influence of Pole Figure Status on ODF Analysis

The influence of measurement condition and calculation method of the pole figure on the quality of ODF analysis is studied and the reasons are discussed. Some defects, which could result in obvious errors, are induced by the method of calculating ODF based on a quarter of the whole pole figure. It is suggested that the accuracy of ODF calculation can be increased by making the whole pole figure data average-weighted,and this method can also analyse the asymmetrical texture quantitatively and effectively.
