Application of the back-scattering electron diffraction technique for characterization of microstructure of polycrystalline materials (single-phase silicon steel and multiphase duplex steel).

· Analysis of crystallographic textures and the related problems - (A. Morawiec, K. Kudłacz)

Numerical and formal aspects in description of texture, microstructures and properties of polycrystalline materials.

· Development of measurement technique of grain boundary topography and method its characterization based on the maps of crystallographic orientations registered by means of SEM and TEM - (K. Sztwiertnia, M. Faryna, A. Morawiec, M. Bieda, A. Korneva)
