【 摘 要 】

From analysis of the crystalline texture (the distribution of crystalline orientations in a polycrystalline substance) of target samples, some critical material properties of those samples may be deduced. Texture typically results in a specimen from the conditions by which its substance is formed or engineered, and may be used to quantify its qualities. This project aimed to produce a full process for texture analysis of target samples. It was intended that this process be implemented for CCD or imaging plate diffraction data recorded in the Stanford Synchrotron Radiation Lightsource Beamline 11-3. A process was implemented for smoothly analyzing diffraction images and producing full pole figures. The MATLAB package MTEX formed a base for the implementation of this process. This process was applied to diffraction data from a rolled Cu specimen. The resulting raw-interpolated and completed pole figures did not sufficiently match to indicate a correct approximation of the orientation distribution function (ODF) for that specimen. A comparative analysis of MTEX and other pole figure inversion algorithms, as applied to this Cu data, may reveal that another method better approximates the ODF.
