  Course Content:

Applications of X-ray and neutron diffraction methods to the structural characterization of materials. Emphasis is on the analysis of polycrystalline materials but some discussion of single crystal methods is also presented. Techniques include quantitative phase analysis, crystallite size measurement, lattice parameter refinement, internal stress measurement, quantification of preferred orientation (texture) in materials, Rietveld refinement, and determination of structural features from small angle scattering. Homework assignments will consist of analysis of diffraction data, and students are to prepare formal laboratory write-ups.  Samples of interest to students for their thesis research may be examined where appropriate.


Labs and Assignments: (tentative!!)
