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

Abstract

In this paper, a complete pole figure measurement was examined by only the back-reflection method using an imaging plate (IP). In the present method, complete pole figures are obtained by only the back-reflection method without use of the transmission method. In particular, complete pole figures are theoretically obtained when its diffraction angle 2θ is 90°. In cases of other 2θ, complete pole figures are obtained by measuring two imperfect pole figures and combining them. In the measurement of imperfect pole figures, plural pole figures were simultaneously obtained by the two dimensional measurement ability of IP. In addition, a correction of diffraction intensity according to a shift of the pseudo-focusing condition is not necessary like the Schulz zeflection method. Pole density data of complete pole figures were effectively applied to analyze the three dimensional crystal orientation distribution of a textured dual phase stainless steel sheet.
