Abstract Scope |
Laboratory diffraction contrast tomography (LabDCT) is a recently developed technique for 3D non-destructive grain mapping using laboratory X-rays. The aim of the present work is to quantify the effects of the experimental parameters on the characterization of the 3D grain structure in iron. The experimental parameters studied include accelerating voltage, exposure time, as well as the number of projections. The quality of the grain reconstruction as a function of these parameters is evaluated by comparing the experimental and simulated diffraction patterns. Based on such evaluation, optimized experimental parameters are obtained for the 3D reconstruction of grains with certain sizes. The results of this optimization will be presented, and possible ways to extend the limits of the LabDCT technique will be discussed. |
