NDE of microstructured materials by x-ray diffraction and refraction topography
For the purpose of micro structural characterization X-ray topography reveals the spatially resolved scattering of materials and small components. It combines the advantages of radiographic imaging and the analytical information of wide and small angle X-ray scattering like phase distribution, texture, micro cracks, interfaces and pores. Scanning techniques at selected scattering conditions permit the topographic characterization of any crystalline or amorphous solid or liquid. Topographic methods and applications for the purposes of research, quality control and damage evaluation are presented.
Determination of pore sizes on sintered ceramic materials using image analysis and X-ray refraction
The results of pore size determination in a sintered glass ceramic, a silicon carbide material and a mullite porcelain are compared against one another using image analysis and X-ray refraction. Taking the results for the total porosity from both methods into consideration, specific differences in the pore size distribution and the mean pore size are discussed.
