In this volume of the Zeitschrift für Metallkunde several publications focus on a better understanding of the hardness of materials and nanohardness test procedure itself. These results have been presented during the nanoMech 4 – the 4th European Symposium on nanoMechanical Testing; September 17–19, 2003 in Hückelhoven, Germany.
Mechanical testing in the nm-range has been developed during the last two decades. The classical microhardness of a sample is determined by observing the contact area by light microscopy. A new technique was developed to determine the contact area from load – displacement curves recorded during an indentation test (Fig. 2). The major advantages of the approach are: (i) these measurements are easy to automate (ii) small indents – even fully elastic indents – can be analysed, and (iii) beyond hardness further materials properties like Young’s modulus, creep, etc. can be investigated.

The combination of atomic force microscopy (AFM) with nanoindentation testing allows to image the surface changes with the indenter tip itself (Fig. 1) and also allows mapping of the stiffness of a sample pixelwise. These images can provide quantitative Young’s modulus maps of materials (Fig. 3). Further techniques include acoustic emission sensing which allows analysing the energy dissipated during fracture events (Fig. 4).

It is a field of active research that is represented by the contributions published in this issue of the Zeitschrift für Metallkunde.
