This research examines the structure of large angle grain                       boundaries using the X-ray diffraction facility at the Cornell                  High Energy Synchrotron Source.  Atomic structure of grain                      boundaries is determined based on the X-ray diffraction results                 and modeling.  The research includes a study of impurity                        segregation to twist boundaries and the thermal properties of                   grain boundaries.  The program provides important, high quality                 data needed for accurate models of grain boundaries and gives                   fundamental knowledge concerning grain boundary structure shifts                due to composition or temperature changes.
