different elements in these Cu-based nanocomposites requires high resolution ZUSA 
characterization techniques. EIGE! 
3DAP analysis enables a detailed atomic-scale chemical analysis and accurate 
information on composition within an overall volume of typically 10x10x100nm3, L Weiss 
Nevertheless, any statistics are almost impossible due to the very small areas which can Vv Knob 
be analysed, which is one major disadvantage of the method besides accurate and 
reproducible specimen preparation from the region of interests and reconstruction of the Institut 1 
obtained data. On account of this, analysis with complimentary methods (XRD, TEM and 
APT) will be performed on selected specimens in future. It is important to note that 
microstructural characterization of nanostructured composites with sufficient accuracy can 
only be achieved by a combination and correlation of the above mentioned methods. 1. EINI
