Potential of Crystal Defects for Enhancing Bulk Functional Nanomaterials: Michael Zehetbauer1; 1University of Vienna
    Top-down processing schemes like “Severe Plastic Deformation – SPD” revealed as most successful to achieve bulk nanostructured materials with excellent mechanical properties [1]. Now, scientists increasingly focus on SPD processing of functional nanomaterials like thermoelectrics, hydrogen storage materials, and biomedical alloys [2]. Significant enhancements have been reached in the efficiency of thermoelectrics, in the capacity and stability of hydrogen storage materials, and in mechanical and corrosion properties of biomedical alloys. However, these functional improvements have been induced by dislocations and/or vacancy clusters rather than by grain boundaries. Type and arrangement of these defects are essential for the optimization of functional properties, and seem feasible by combining certain SPD techniques and specific thermal treatments.
