Defect Heterogeneity Characterization in Deformed Materials by Synchrotron Light and Electron Diffraction

On the week October 17^th till October 21^st, we will be receiving Prof. Raul Bolmaro, from the Institute of Physics of Rosario, Argentina. Prof. Bolmaro will be giving three lectures financed by EUSMAT (European School of Materials). Prof. Bolmaro is the director of one of the most prestigious research institutes in Materials Science in Argentina. He will be offering three lectures with a broad range of topics, so we hope they can be really interesting for most of you. 

Lectures will take place at 10.30 (am) in the “Sala Polivalente” building I, of the EEBE Campus. Lectures will last 50 minutes plus some extra time for discussion and questions. 

Assistance is free to the entire University community. The assistance of PhD students can be acknowledged as credits in their doctoral activities (after the lecture, provide your email to send the assistance confirmation letter).

Defect Heterogeneity Characterization in Deformed Materials by Synchrotron Light and Electron Diffraction.

Severely deformed materials accumulate different kinds of defects, like dislocations and twins, together with a diminishing grain size. All those microstructural features are strongly dependent on grain orientation and their characterization is of high interest because of their influence on mechanical properties, both after deformation and after being subject to further thermal treatment. We show experimental data taken by synchrotron light diffraction and EBSD in several alloys subject to thermomechanical treatment. Both techniques convey, after the proper analysis and interpretation, results that not only confirm each other but also allows to design experiments with the purpose of having a whole map of anisotropic and heterogeneous accumulation of deformation energies.
