N2 - Beryllium has an extraordinary combination of material properties such as low density, high melting point, high specific heat capacity, high Young's modulus, high hardness and low atomic number. The conventional investigation of the mechanical properties of Be and Be alloys is only possible under difficult conditions due to the material's toxicity and the resulting restrictions on sample manufacturing. These limitations are avoided, at least partly, when using a depthsensing hardness test, also called nanoindentation, where the resulting contamination with Be dusts is limited to a controllable extent. For this work, technically pure Be from Xray exit windows of highperformance Xray tubes was chosen and its mechanical properties were characterized by means of nanoindentation. This contribution will focus in detail on the preparation of the material as well as the following microstructural characterization by means of light microscopy and scanning electron microscopy. The mechanical results of local nanoindentation will be correlated with the microstructure and compared with known values found in the literature.
