Summary

Using X-rays is not new for the study of metallic structures. Most existing X-ray systems can obtain shadow images through objects. For complicated structures like metallic foams the 2-dimensional information does not allow defining the object's three-dimensional architecture. 3-dimensional reconstruction by tomographical methods looks like being the most realistic way to get space information about the internal structure of the foams in a non-destructive way. A new generation of micro-CT scanners opens possibilities for investigation of the Al, Ni and Ti metallic structures with very high spatial resolutions. For investigation of the internal 3-dimensional structure of Al foam we used a high-resolution X-ray desk-top microtomograph “SkyScan-1072” with warranted resolution better than 8um as well as a portable low-cost micro-CT scanner “SkyScan-1074” with resolution in the 40um range. Both instruments can clearly reconstruct the internal 3-dimensional structure of the metal foam.
