SEMINAR ABSTRACT:

The combination of tomographic, microstructural data with other experimental techniques and with modeling is paramount, if we want to extract the maximum amount of information on material and component properties. In particular, quantitative image analysis, statistical approaches, direct discretization of tomographic reconstructions represent concrete possibilities to extend the power of the tomographic 3D representation to insights into the material and component performance. This logic thread holds equally for industrial and academic research, and valorizes expensive experiments such as those carried out at synchrotron or neutron sources, which cannot be daily repeated.

I will show a few examples of possible use of X-ray tomographic and Neutron Diffraction data for quantitative assessment of damage evolution and microstructural properties, as well as for non-destructive testing. Examples of micro-structured inhomogeneous materials will be given, such as Composites, Ceramics, Concrete, and Additively manufactured parts. I will also show how X-ray refraction computed tomography (CT) can be highly complementary to classic absorption CT, being sensitive to internal interfaces.

SPEAKER INTRODUCTION:

Prof. Dr. Giovanni Bruno studied Nuclear Engineering (1989), and successively Physics (1998) at the University of Bologna, Italy. He got his Ph.D. in Materials Science at the University of Ancona, in 1997 on residual stress analysis in welds of metallic alloys. He was postdoc at the Open University, Milton Keynes, UK, and at the Hahn-Meitner-Institut Berlin, before becoming project leader at the Institute Laue-Langevin, Grenoble, France, always working on residual stress analysis and mechanical properties of metals and ceramics. He then moved to Corning Incorporated, in leading positions in France and USA. He is head of division 8.5 “Micro NDT” at BAM and professor at the University of Potsdam as of 2012. His research interests lie in the fields of microstructure-property-performance relations in composite materials, including additively manufactured alloys.
