Local Structural Characterization within Polycrystalline Bulk Materials by High Energy Synchrotron Radiation

3-Dimensional Characterization of Polycrystalline Bulk Materials Using High-Energy Synchrotron Radiation

The implementation of 3-Dimensional X-Ray Diffraction (3DXRD) Microscopy at the Advanced Photon Source is described. The technique enables the non-destructive structural characterization of polycrystalline bulk materials and is therefore suitable for in situ studies during thermo-mechanical processing. High energy synchrotron radiation and area detectors are employed. First, a forward modeling ...

Nuclear Fluorescence Using High-energy Synchrotron Radiation

We present some measurements of nuclear fluorescence which were made while exploring the potential of a unique source of very hard x-rays which was installed at ESRF until recently. It produced radiation of energies up to 1MeV. In this range there are many nuclear resonances, and so we made a small survey of some plausible candidates to see if they could indeed be excited using this source. Alo...

Materials Analysis Using Synchrotron Radiation

Synchrotron radiation (SR) is a tunable, highly oriented, intense X-ray. Its tunability has led to XAFS being used as a common analytical tool, and is particularly useful for examining local structures. In fact, its use is indispensable to the examination of not only amorphous materials or solutions but also multicomponent systems. Thanks to the high intensity of SR, it is possible to determine...

Multipurpose furnace for in situ studies of polycrystalline materials using synchrotron radiation.

We report a multipurpose furnace designed for studies using synchrotron radiation on polycrystalline materials, namely, metals, ceramics, and (semi)crystalline polymers. The furnace has been designed to carry out three-dimensional (3D) x-ray diffraction measurements but can also be used for other types of synchrotron radiation research. The furnace has a very low thermal gradient across the spe...
