x射线μCT分析为金属泡沫的无损表征提供了一种通用的工具。本文将介绍定量特征确定的最重要方法，并将其应用于粉末冶金工艺生产的泡沫铝。利用单色同步辐射的特殊性质，对发泡剂tih2的分布和几何参数进行了高分辨率的定量研究。分析步骤可以用作表征金属泡沫结构的标准程序。
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.
