Nanostructured Materials and Interfaces Research Group Content

Oriented single crystals, bi- and tricrystals are grown from melt using the floating-zone melting and Bridgman techniques. Micro- and nanocrystalline structures are prepared by specific thermomechanical treatment in solid state. Besides full crystallographic characterization of the grain boundaries and triple junctions in bi- and tricrystals we study their chemical composition (solute segregation), mobility (migration) and/or mechanical and fracture behavior. In multicrystalline materials we are interested in texture formation and in the grain development and morphology during plastic deformation and annealing. An important part of our research represents theoretical modeling of the dislocation behaviour and/or grain boundary segregation.
