Quantitative methods for the analysis of synchrotron-µCT datasets of metallic foams

Abstract

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 cellwall space quantitatively at a high resolution, but also the distribution and geometric parameters of the blowing agent TiH2. The analysis steps can be used as a standard procedure to characterise the structure of metallic foams.
