Comparison of mechanical properties of surface layers with use of nanoindentation and microindentation tests

The objective of the paper is a mutual comparison of diff erent methods for evaluation of mechanical properties of surface layers. Mechanical properties were tested with the use of nanoindentation and microindentation tests. Different loads and constant deformation speed were used in both cases. For the evaluation of mechanical properties, the AISI 304 type Chromium- Nickel steel commonly used in mechanical engineering industry was tested. Knowledge of relations and diff erences between nano and micromechanical properties is necessary for understanding of mechanical processes continuously occurring in surface layers during cutting processes.
