Seminar

Slip systems and dislocation densities in individual grains of polycrystalline aggregates by a novel synchrotron procedure

Wednesday, 04 November 2015, 13:30-15:00
Institute of Nanotechnology Seminar room 0-167
Talk given by Prof. Tamás Ungár Department of Materials Physics, Eötvös University Budapest, Hungary Abstract: The analysis of peak broadening in X-ray diffraction patterns proved to be one of the most powerful tools to provide quantitative characterization of substructures in terms of the density-numbers of different types of lattice defects, especially dislocations. A novel synchrotron X-ray diffraction-based technique for grain-by-grain assessment of dislocation density within polycrystals was applied to determine the slip-mode, the slip-systems and the dislocation densities in the B2 structure CoTi and CoZr alloys and tensile deformed AZ31 Mg. The procedure, some results and the potentials of the method will be discussed.
