Effect of crystallographic orientations of grains on the global mechanical properties of steel sheets by depth sensing indentation

Popis výsledku v původním jazyce

The main idea of this work is using a physical model to prepare a virtual material withrequired properties. The model is based on the relationship between the microstructure andmechanical properties. The macroscopic (global) mechanical properties of steel are highlydependent upon microstructure, crystallographic orientation of grains, distribution of each phasepresent, etc... We need to know the local mechanical properties of each phase separately inmultiphase materials. The grain size is a scale, where local mechanical properties are responsiblefor the behavior. Nanomechanical testing using depth sensing indentation (DSI) provides astraightforward solution for quantitatively characterizing each of phases in microstructure becauseit is very powerful technique for characterization of materials in small volumes. The aim of this experimental investigation is: (i) to prove how the mixing rule works for localmechanical properties (indentation hardness HIT) in microstructure scale using the DSI techniqueon steel sheets with different microstructure; (ii) to compare measured global properties withproperties achieved by mixing rule; (iii) to analyze the effect of crystallographic orientations ofgrains on the mixing rule.
