Comparison of nanoindentation techniques for local mechanical quantification of aluminium alloy

Popis výsledku v původním jazyce

Nanoindentation is widely used for the assessment of micromechanical behaviour of multiple phases within the material microstructure. Structural materials typically exhibit large variations in elastic modulus and hardness with increasing indentation depth during depth-sensing indentation experiments because the measured stiffness response is affected by its heterogeneity. In this study, the complicated microstructure of heterogeneous aluminium foam cell walls is described and related micromechanical analyses using various characterization modes performed. The paper compares the results of several nanoindentation approaches for the assessment of hardness and elastic parameters using both the quasi-static indentation and the dynamic modulus mapping method. The results of quasi-static indentation were performed for two different indenter geometries (Berkovich and spherical tips). The material phase properties were analysed with grid indentation method based on statistical evaluation of a
