Abstrakt: Precession-enhanced diffraction (PED) is a transmission electron microscopy technique that allows for pseudo-kinematical diffraction conditions to occur. Using collected spot patterns, PED has successfully been demonstrated to provide for phase and orientation mapping in a variety of materials. One major advantage of PED is the fine spatial resolution, on the order of a few nanometers, allowing previously inaccessible grain boundary orientation mapping of nanostructured materials to be realized. This article provides a basic overview of the emerging technique with selected highlights of its application to materials science and engineering. [ABSTRACT FROM AUTHOR]
