Volumetric data

X-ray synchrotron tomography was used to visualize the effect of thermal treatment on the 3D network of Al-Si alloys. For this the same sample was measured at the same position before and after heat treatment. The intermetallic phases in the reconstructed volumes have been segmented using global grey value thresholding. The three-dimensional tomography of Al-Si alloys during heat treatment is required to gain information about the stability of phases and especially the evolution of interconnectivity of 3D networks of rigid phases embedded in the Al-matrix.

The volumentric data consists of two binary tiff volumes of tomographic data sets collected of the same sample in different thermal heat treatment conditions.
