Complete Pole Figure Measurement Using Only Back-Reflection Method with Imaging Plate and Application to Three-Dimensional Analysis of Texture.

Abstract

Complete pole figure measurement using only a back-reflection method with an imaging plate (IP) was attempted. In our method, complete pole figures were obtained using only the back-reflection method without the use of a transmission method. In particular, the complete pole figure theoretically is obtained when its diffraction angle 2θ is 90°. In the cases of other 2θ values, the complete pole figure is obtained by measuring two incomplete pole figures by the back-reflection method and combining them. Such incomplete pole figures could be simultaneously measured by means of the two-dimensional detection ability of IPs. In addition, the correction of X-ray diffraction intensity to compensate the deviation from the pseudofocusing condition was not needed in our method, unlike Schulz’s back-reflection method. Pole density data obtained from our complete pole figures were effectively applied to three-dimensional analysis of the texture of a dual-phase stainless steel sheet. Crystallite orientation distribution functions (ODFs) of each phase were obtained.
