Characterization of low density carbon foams by x-ray computed tomography (CT) and ion microtomography (IMT).

摘要

Two NDT techniques were used to characterize low-density, microcellular, carbon foams fabricated from a salt replica process. The two techniques are x-ray computed tomography (CT) and ion microtomography (IMT); data are presented on carbon foams that contain high-density regions. The data show that densities which differ by 99.9% carbon. 4 refs., 7 figs., 1 tab.
