Microcomputed tomography (µCT) is an important method in many engineering fields used for 3D geometrical characterization of engineering materials. Properties of cellular materials depend on their internal structure which is usually highly irregular. Proper characterization of their geometry and topology is thus of utmost importance for their use in engineering applications.
The characterization process based on a µCT scanning results in a form of three-dimensional (3D) image stack, i.e. a stack of two-dimensional cross-section images along one chosen axis. The 3D image stack is analysed to obtain geometrical and topological data by applying different image analysis algorithms. The selection of algorithms depends on the internal structure of analysed material since in the case of open-cell materials the geometry and topology of the struts is of interest while in the case of closed-cell materials the geometry and topology of the cells is required. Successfully applied methods and algorithms will be presented along with achieved results for different open and closed-cell metallic cellular materials.
