Titel
Bragg-edge Imaging with Neutrons
Abstract
Cold neutrons have a wavelength that is in the same range as the d(hkl) spaces for polycrystalline metal materials. Therefore imaging of polycrystalline materials with monochromatic cold neutrons provides a unique contrast due to coherent Bragg scattering. Here, we present investigations of metallic materials with energy-selective neutron radiography around the Bragg-edges for polycrystalline materials. Polychromatic and monochromatic radiographic measurements of welded composite materials are shown. The results give interesting insights into the manufacturing process.
