Quantitative methods for the analysis of synchrotron-µ CT datasets of metallic foams

The analysis by means of X-ray μCT offers a versatile tool for the non destructive characterisation of metallic foams. The most important methods for the quantitative feature determination will be presented and applied to an Al-foam produced by a powder-metallurgical processing route. The special properties of monochromatic synchrotron radiation have been used to study not only the pore- and cell-wall space quantitatively at a high resolution, but also the distribution and geometric parameters of the blowing agent TiH 2 . The analysis steps can be used as a standard procedure to characterise the structure of metallic foams.
