1 September 2010 Data-constrained microstructure modeling with multi-spectrum x-ray CT
Author Affiliations +
Conventional X-ray CT is not usually sufficient to determine microscopic compositional distributions. A dataconstrained microstructure modeling (DCM) methodology has been developed which uses multiple CT data sets acquired with different X-ray spectra, and incorporates them as model constraints. The DCM approach has been applied to predict the distributions of corrosion inhibitor and filler in a polymer matrix. The DCM-predicted compositional microstructures have a reasonable agreement with EDX images taken on the sample surface.
