3D Characterization of Graphite Morphologies in Cast Iron

This article presents for the first time a full 3D characterization of irregular graphite morphologies in cast iron using Focused Ion Beam (FIB) tomography. It provides the new basis for understanding the different growth mechanisms and the limits of graphite classification used in common 2D strategies. Thus, the accuracy of the graphite classification could be estimated. In addition, the stereological parameters of the 3D structure can be directly obtained.
