ABSTRACT

The aim of the submitted work is to study the influence of applied loads (test forces) between 0.09807 and 2.9421 N on the measured value of micro-hardness of sintered Fe/3.3 wt-%Cu + CnHm. The Indentation Size Effect (ISE), i.e. the influence of the load on the micro-hardness is expected. The results were evaluated by Meyer’s index n, t-test, and non-parametric tests. The applied load has a statistically significant influence on the type and size of the ISE. Tested sintered material shows ‘normal’ ISE with Meyer’s index n = 1.7588.
